  1. So that is my question, does the cam lobes need a different grind depending on which 425 block he has has.
  2. Thanks joe, kind of what I thought, all a bunch of experts in his ear! So one more question, if his block is the 39d or the 45d, it sounds like the cam lobes would be ground differently based on your description or am I reading it wrong and the cams are all the same?
  3. You’re actually better off letting the metal plate sit right on the bevel. Just open the holes for the pin slightly. If the metal is a little closer to the top that’s good plus the screw will contact the metal in the hole which will allow for it to be more secure. Trust me, don’t overthink it. Ask me how I know! LOL. The urethane comes from Specialty Resin and with the printed mold, you might have some release issues because of the “ribbed” texture the process leaves. Our aluminum molds were super smooth and polished but we were also molding much deeper in the mold than you will be.
  4. Hello, trying to help my brother out. He’s been working on his 67’ cutlass that is a street/strip car and is currently rebuilding his motor. While he was at the track this past year he said many guys were asking him if he had the wedge motor and old him the intake plenum angle was different on that motor. (425 only). When I looked it up all I find is a statement that ALL Olds engines were a 90 degree bank angle and the “wedge” term refers to the shallow 6d valve angle in the heads. Putting a angle gauge on his current manifold I got a reading of 45d which makes sense with a 90d bank angle but he’s insisting to me that many guys all asked him the same question and that they were older, knowledgeable Olds racing guys. Of course, I’ve run 6.2 diesels for years with no issues and many miles yet continually have diesel “experts” tell me how bad they are, how they were converted gas engines, made by Detroit diesel, etc., which are totally incorrect statements. So the question is did the 425 engine, my brothers is a toronado, run different angles at the intake plenum angles?
  5. That is the Peterson electronic regulator and mine also works perfectly. It reads the voltage in the battery and maintains the amount of charge it needs while driving. At daytime mine will drop to only a few amps after a long ride and will show about a constant 0 amps at night rather than showing a discharge like a standard generator and cut out. The Peterson regulator still needs a cutout or a diode.
  6. Jerry, don’t have the metal tight on the pins as it won’t release from the mold easily. We put metal into our parts and experimented with different things to get it right. A slightly larger hole will rest on the beveled area of the screw hole pin and will allow for it to separate easier. Joe used two part urethane and the stiffer product he used was called Shore 70. All our we gravity pours and we had few air bubble issues. You will need to really get a clean mold and use plenty of mold releasing agent for the urethane to flow good.
  7. Thank you guys. I was able to get the 31’ Chevy up and running today. I put the carb back together and on the car. It started right up with some choke and ran perfectly. It never needed choking before and would easily flood over so I now assume it was probably a float issue for a long time. With the holes in the float on the top, it probably took a fair amount of time to fill up.
  8. Well, a couple days ago I installed my restored fuel tank and that went off without a hitch. I went through the whole underneath of the car cleaning off the spatter from my radiator pushing water out and then greased all the fittings and drive shaft as I only put some light lubrication in the fittings originally. I then decided yesterday to install the other radiator that I had cleaned and serviced. I removed my blocked one from the chrome shell after I took it off the car then installed the serviced one. Put it in the shell and car then hooked up the hoses. I started to fully assemble the car and my brother, who was helping me said "don't do it, test it and run it before putting it all back together". Well I put in a gallon of water and went to add another when we noticed a lot of water running on the floor! WTH! Pulled it back out to find a 1" long vertical fracture crack in the front corner of the bottom tank. I know it wasn't that way when the radiator shop finished it and it wasn't dropped or anything like that. It does fit tightly in the shell but that shouldn't have caused it either. The radiator shop said things like that can just happen and to bring it back. What a bummer. I then realized the one person I know with the worst mechanical bad luck having stuff just go wrong is my brother and I had him helping me. I told him it was his fault! LOL Anyway, now it's back to the shop with both radiators to have him fix it again. And did I mention, I went to take my 31' chevy out for a ride and the carb was flooding over. Replaced the float valve, it started up then stalled flooding over more. Turns out the brass float had three pin holes and it was FULL of gas to the point you couldn't even feel it shaking around until you shook it for a long time to start getting some gas out. So last night, armed with some advice from Jon from the carburetor shop, out came the soldering iron and I repaired the float. All I wanted to do was to drive one of my antique cars yesterday and go to the cemetery to visit my dad's grave. I didn't get there, Damn it! At least I can get some pictures of the new tank in and I'll post those. Here's a shot of the Olds outside for the first time this year.
  9. Kind of at a standstill on the truck. Waiting on the motor still and the owner is supposed to be purchasing the two door wood kits from KC wood but they haven't hooked up yet. I currently have the cab level and correct so don't want to remove it from the chassis until I rewood the doors and make sure all is correct. I have another car I need to start on so I might do that until I get back on the truck. Should be getting underway soon hopefully.
  10. That’s exactly it with doing a quality restoration even when doing most the work. It’s the journey of the restoration rather than the value of the finished product. Of course, try explaining that to the significant other. I have over $50k into my Olds, and as you know, did most the work. While the Olds is only one of 249 built, one of three currently known, and the only one restored to an as correct and high level, I believe it would be difficult for it to bring enough to even break even. It’s just an Olds and doesn’t carry the prestige of even GMs next marque, a Buick, yet there were a lot more of them. I think of my 6 wheels alone with 943 hours total in them. If I paid someone $50hr for that work it would have cost $47,150 alone! Now that’s really 😜! The MG is looking beautiful so when done, just sit back and enjoy as you deserve it plus you know you did it yourself.
  11. I believe that the cost of chroming is one of the major factors of the rat rod phase. Just like the cost of high end paint jobs being mainly responsible for the flat or mat black craze. I’ve been told that those big old 50’s Cadillac bumpers are in the $5000 to chrome so I’m glad I’m not into those. Next car for me, Ford T! No chrome and just one color. Cheap aftermarket parts, and easy restoration! Ok, just joking, no new cars on my horizon but I have thought of recreating my family’s business 23’ T, Martin Parry bodied depot hack. I still have the hand painted side curtains. Sorry, just realized I hijacked L2Ws thread!
  12. Funny about the tacks Matt. In 32’, I guess because the depression was on, the opposite was true. Most tacks on the seat were spread out 4-5” and the panel boards were much worse. My Olds and my buddie joes had about 4-6 tacks in each rumble seat area side panels with spacing easily over 12”! What a difference a few years make.
  13. I think the price of chroming is kind of ridiculous also and they tell you it’s all in the buffing and polishing cost of labor. My neighbor is a professional polisher by trade and I watch him polish up stuff in 15 minutes on his equipment that would easily take me two hours and it would be nowhere as good. The chrome on my 32’ Olds cost twice what the car originally cost me and I can tell you the car cost in the 5 digits. My dash panel alone was $1000! After paying for the chrome I could understand why some people think we should have our heads examined!
  14. Had a gentleman contact me because he had seen the mold we had made for the 32’ Olds. He mentioned that there were Many people who wanted the part that he wanted to mold. I explained the costs associated with making a mold and suggested that he get at least four of the many people And have them all invest equal amounts into the project. Of course I’ve never heard back so it’s easy to assume the “many” probably ended up being only the person who inquired. Once people realized the cost and investment they all of a sudden don’t need the part that badly.
  15. One of the things I enjoy most about working on and restoring these cars is doing model /year specific research as I came to realize just how fast the automobile was progressing. Not just year after year but in some cases just months. On my 32’ Olds on some things there was not just two but at least three running changes to the same part or assembly. Like your 33’, they were working quickly to solve a chattering clutch. I’m sure there’s many more things you’ll find that were changed or improved on your car as the model year progressed. Back then the manufacturer wanted to improve on any deficiencies as soon as they realized it was there. Today, they’re afraid to admit any issues because the public is so sue happy. And when we have a judicial system that allows someone who buys a hot coffee to sue, and win for it being hot, you can’t blame them.
