  1. The stock 322 is actually 321.6991 if my 3rd grade math is correct...bore it 0.040 and you have 328.1652; 0.060 will give you 331.4224. As far as compression the last rebuild that I participated in used Egge pistons and had a cranking compression of 150 psi on the engine stand, which is just short of stock and should improve with break-in. Come to Plano for a demonstration.

  2. You cannot duplicate the factory insatllation without removing the skin, but you can cut out the exposed material , make a pattern and glue in place. I cut mine slightly larger so I can tuck it under the edges of the opening. These panels were painted along with the underside of the trunk at the factory, but most restorers leave it black.

  3. Neither Steele or Metro are best are across the board. On my 55,s Steele has the best mounting pads whereas Metro has the best windshield gasket and trunk weatherstip. If a part is "just ain't right" order one from the other supplier and it will usually fit better.

  4. Some observations from my own wrench-turnin? and research:

    On the 55 engines I have had apart the intake valves are all tulip shaped and the original exhaust valves valves are flat on top. Some of the replacement exhaust valves after long ago valve jobs are tulip shaped. Seats and valves from the later (364/401) nailheads can be installed; ask your machinist.

    In 1993 I bought a cam for the 322 in my CVT from (a now defunct company) NW Buick Performance owned by Dave Johnson (this name gets mentioned occasionally on other Buick boards). His part number was CS 2114 and I finally found the specs: lift=0.454 int. and ex; duration= 260 int. and ex.; cl=114; power range=1000-5300; max rpm= 6000. I did no other mods to the engine, still single exhaust and stock lifters, and the original pistons were used. With the stock 3.36 rear gears it was a slug in low speed driving, but really starts pulling hard after 3000 rpm. I replaced the rear gears with 3.60 and now the low speed throttle response is similar to stock and it starts cookin' sooner at WOT. The cam was a reground '56 core, the 322 is the early '55 with the bolted piston pin, the cranking compression after cleanup decking and head milling is 170, which is about stock.

    I suspect that the low compression (120) on another of my 55's 322 is due to recession on the intake valve seats from wear and excessive grinding ( the machine shop that replaced the exhaust seats as an after thought told me that the intake valve seats were 'marginal') Marginal is an understatement, they are recessed about 1/8 to 3/16 in judging from the amount of difference of stem height above the keepers, comparing the new exhaust valves and the old intakes. My feeling is this makes the chamber volume larger and lowers the compression. Replace all the seats or use some nearly new heads. By the way notice those beautiful machined combustion chambers on the 322 heads!

  5. Modern Speedometers, specifically 1992 Mercury Marquis analog.(there are only electrical connections, no speedometer cable) The odometer quit working although the the trip odometer and speedometer is OK. Installed a used one and both the odometer and the trip odometer did not work. The place where I bought it says there are other issues with my car. Maybe if someone can tell me how these things work I can understand enough to agree or argue.

  6. When we buy a used car we inspect it closely or have a shop inspect it and maybe even search the vehicle history for previous repairs. But a new car, well it is NEW right? Car dealers are the modern equivalent of old time horse traders...they generally will not lie to you if you ask a specific question, but will not volunteer information. In your case if you had asked if the car had been repaired they would have said yes and you probably would not have bought that unit. It is a sad state when you have to ask all the same questions and do all of the same inspections you do on a used car, but i'll do from now on.

    In 1976 I bought my first new car an Olds Delta Royale. It was a time if great excitement and I too was blinded by the glitter. I custom ordered this car and when I inquired on the anticipated delivery date, I was told it had arrived but had a 'little' transit damage. When I had it repainted a few years ago it showed extensive repairs to the roof. including plastic filler and welding with brass...sort of explains the leaks at the C-pillar. Then when I replaced the upholstry I found broken glass under the rear seat. Probably had another car fall on it! I would not have bought if I had known about the damage.

    A local Buick dealer sold a 99 LeSabre to my father (he bought with out my inspection). The car had poorly repaired front end damage and even though it showed only 30k miles it appeared to be beat to death...all of the struts were shot, the tires were chewed from driving on gravel roads and the newly changed oil was already dirty. I called the dealer and he said "well people trade these things in and don't tell us about accident repair"....I would bet that if I tried to trade in this vehicle on a new car they would spot the damage! Oh well, another day and another name to add to my list of people who [censored] me off.

  7. Recently I've recieved some emails asking for details on this rebuild. My respsonse to these inquiries was to post the questions on the forum so all could benefit or that I would address them on the forum.

    The pistons were bought from Kanter but had the Egge part number and looked identical to an example I have from Egge except that the ring grooves were closer to the top of the piston which might give slightly higher compression.

    The valve parts were all 1956: camshaft, lifters, pushrods and dist gear. Hardened exhaust valve seats were installed and all of the old valves were reused.

    This is a late producton engine and did not have a windage tray, but had the bolt holes in the block for attaching (attaches with 4-5/16 bolts). I have done other late engines and the windage tray was present. It is probably not necessary except in extreme applications.

    While the engine was still on the engine stand, oil was added (it took 7+ quarts to fill a dry engine), the oil pump was spun with a drill and it developed 30# pressure. Then a starter was attached and activated and it developed 20# at cranking speed with the plugs out. A compression check was done and showed 150# on all cylinders.

    A 2bbl carb was used because it was available and Mike wants to keep the stock look (for now). The "seat of the pants" performance is more than adequate.

    A neoprene seal for a Buick 455 was used in the timing cover. This IS NOT a direct and easy replacement: the 0.020" interference fit is too tight to just tap in; it was taken to a machine shop where the timing cover was chamfered and then pressed in.

    The rear seal was the usual "rope". The side seals (between the rear main bearing cap and the side of the block): I used cotton string with #2 permatex packed in tighly with a nail until flush with the top. Anaerobic sealer was used on the clamping surfaces between the block and the rear main bearing cap).

    Gaskets were always glued to the part with 3-M weatherstripping cement and then either assembled dry (cork) or brush on sealer was used. If you use rubber valve cover gaskets, glue these to the valve cover and use anaerobic sealer on the other side. You CAN build a dry nailhead.

  8. Some of this response should be under the heading 'Those pesky young people'. Anyhow you should have seen the smile on Mike's face after his first drive...PRICELESS!!

    It all started about a year ago when I invited Mike to my house to drive my 55 Centurys to see if he liked the power and response of a 322 compared to the anemic 264 in the Special. He was hooked! It also helped that I offered to give him a 322 from one of my parts cars (that was his last good deal).

    Then in February the work started (and money spending...his money!). I figured it would take about 2-3 months and would be ready to drive to Flint for the big party. We (the word 'we' is to indicate that I was present and watching Mike do all of the dirty grunt work) started by pulling the engine out of the parts car complete with a 2 inch cover of rodent turds. Then disassembly which revealed a very sludged up and abused mess, but it did look promising. So off to the machine shop for cleaning and further inspection. That it turned out was our first mistake even though this shop has a good reputation building race engines (chebbie???) and rescued me from a previous machine shop disaster. It took the machine shop a month to clean and inspect: crank is ok, just needed polishing, block needed one sleeve and bored 0.040", heads ok just needed hardened seats and valve guides. Now to order the needed parts, and that was the second mistake (ordering or "attempting to order parts" from Buick World...Mike can give better details of that fiasco). Two more months go by before parts are delivered to the machine shop which by now has put the 322 on the back burner. So another month before anything is done. Now it is June and getting HOT in South Texas, and the Flint trip for that car is scrubbed. (Actually Mike did not go to Flint either...stayed home with his wife...something about birth of 1st son...)

    Finally the machine shop called and said everything was ready, so 2 days later we go to pick it up and it was not ready...waited 2 hours for them to 'tie up loose ends'. After we got it back to my shop and unwrapped the parts we found the bad news: even though they said everything would be "assembly clean", everything was filthy with machine oil and grindings; the crank also had rusty finger prints on the polished journals; the oil galleys in the block were still full of sludge since the plugs had not been removed for cleaning; the heads were a mess. Ah, the heads. First thing I noticed was the valve stem height varied more than 1/8", second after removing some valves we noticed that the valve guide seals that were paid for were not installed, an intake valve seat had a rust pit that you could catch a finger nail on, and no valve spring shims were present even though the old springs were used. So back to the machine shop and a formal ass-chewing with the owner who agreed that this was not acceptable. Back home everything looked fine except the heads: when I removed a valve I found that the generic shims for the outer valve spring covered the recess for the inner valve spring. This the exact same thing that happened on a previous rebuild, except it was not discovered until after the engine was started: that little old spring bind resulted in bent push rods, broken rockers, bent and broken rocker shafts and a bent camshaft! Back to the machine shop and 3 weeks for them to find and install the correct shims for both the inner and outer springs.

    Assembly went slowly since EVERYTHING was checked and rechecked...we were sorta gun-shy at this point (everything was on the money). When torqueing the main bearing cap bolts one would not tighten (it stretched 1/4" but did not break...off to the parts store for trip number 79). The rebuilt water pump would not turn after installation...had to grind the shaft off flush with the impeller. I asked Mike after he installed the heads if he put thread sealer on the head bolts..."uh no, why?" Anyhow you need to put thread sealer on every bolt or stud that goes into the block or head of a 322! That includes the engine mounts and studs for the sparkplug covers...even if you are sure that it does not communicate with an oil or water cavity, put it on anyway!

    Painting the engine should be a no-brainer except the paint in the quart container did not match the paint in a rattle can purchased at the same time from "Cars". The paint was Acrylic enamel which may bubble and lift if repainted...engine enamel used to be Synthetic enamel, which was more forgiving...just another aggravation.

    On the Saturday morning that we 'stabbed' the engine back in I had arranged for another friend to stop by to pick up a tool that he needed...you know the rest: audience participates!

    Mike worked until late that day and another but still lacked the plug wires and a few other details, but I waited for his return before firing it up for the first time. I wanted to show him how a properly built nail would start right away...NOT! The #$%&@*%$#@# distributor was installed 180* off! I still think Mike turned the engine while I was not looking.

    Another mystery for awhile: after starting to drive it the engine would die on right turns...a few days of tinkering found a battery cable touching the starter splash shield.

    One reason it took so long is that Mike lives 60 miles from my shop and the machine shop is 30 miles further and we both have 'day jobs'.

    OK so it runs, what is the verdict? It could not have turned out better: Very quiet and smooth owing to the excellent balancing and very good power, throttle response. Part of this is due to the 3.6 rear gears from the Special vs 3.4 gears in the Century and the 2 bbl carb that flows better in the low and mid range than the primaries of a 4 bbl (I thought I heard that some where, but I just got back from measuring the bores at the throttle plate on a 2 bbl and a 4 bbl and the 2bbl is larger). It does run out of steam at higher rpm's where the secondaries of a 4bbl would come into play. I'm still trying to talk Mike into a 3 deuce setup...ok to dream with someone else's money! He will need his money for tires if he keeps burning rubber!

    'Those pesky young people'. Anyhow you should have seen the smile on Mike?s face after his first drive...PRICELESS!!

  9. I think the air cleaner says 'Wildcat 445' which would make it a 401 and the breathers on the valve covers are at an angle not straight up like a 322. Different engine would need a different transmission since the 401 will not bolt up the the transmissions used with the 322. I once used a torque ball from a 57 in a 55 and even that pushed the rear back. Who knows what other modifications were done. Looks like it was done a long time ago and is probably a good runner...but why do that to a Skylark??

  10. You will never stop the chatter with the disc you have...gotta have the buffer and shim springs. All you can do is change your your clutching technique: more revving and slipping when starting off. There is the possiblity than a different friction material will help, but how many times do you want to pull that tranny?
