421-6speed Posted November 5, 2012 Share Posted November 5, 2012 I have been reading a few posts here where members are asking how to update their suspension. Every project is different. It all depends on what your trying to accomplish. In my case I was looking for a car that retained a mostly stock looking body with a nice stance and a updated suspension. More of a Street Rod so to speak. Now I know that most of the members here prefer the original restorations and in some cases I would agree. In this build I mixed it up a bit buy using a 87' C4 front suspension a 66' 425 nailhead coupled to a SP400 and a 57-64 Olds/Pontiac 9.3 Posi. After looking at several different front suspension and doing a ton of research I chose the C4 because I thought it had the cleanest look and packed a big bang for the buck. I found a company in CA. Flat Out Engineering that makes a after market crossmember for the C4 components. Most of the crossmembers that Flat Out Engineering make are for pickups but, it just so happens that the crossmember that they make for 36-54 Chevy pickup measured 29-1/2". That just so happens to be the exact same measurements between the frame rails on my 57' Super. To add a plus to the situation the C4 tracking width is the same as the 57' Super 59-1/2". Well this was a no brainer. For the rear suspension I built a triangulated 4-bar. For the driveline I used a 2-piece from a 66' Wildcat. I did have to shorten it in the front and lengthen it in the rear. By using the 2-piece driveline I was able to adjust the pinion angle down giving me ample room for clearance in the driveline tunnel to achieve the ride height I desired. It is getting a bit late so I will continue this later and post some pics of my progress. Link to comment Share on other sites More sharing options...
421-6speed Posted November 5, 2012 Author Share Posted November 5, 2012 Here are a few pics showing the process. Before I cut anything I used some Angle steel to support the frame. I also blocked the frame at ride height and then built all my suspension to accomodate. I also made some rods up that measured the length width and cross width of the front of the frame and used a center punch to establish reference points.

421-6speed Posted November 5, 2012 Author Share Posted November 5, 2012 I also built all the brackets for AC compressor, alternator and, power steering pump. I am using a Gen ll power steering pump with a remote reservoir. Once the front inner sheet metal was installed I did not like the way the stock radiator mounted so I made up a template for a new radiator that will mount under the core support from the front. This will allow me to build a fan shroud that will mount on the back side of the core support and I will run a mechanical clutch fan. I also decided to use a hydroboost power brake assembly that came out of the same Chevy Astro Van as the remote reservoir for power steering.

421-6speed Posted November 5, 2012 Author Share Posted November 5, 2012 What I have been working on this past week is the bumper ends. I did not like the shields that the factory used so I made my own sealing off the bumper ends from exhaust fumes that rot these out. I cut out the plates inside that attache the mounting brackets and delivered them to the chrome plater to metal finish. When he is finished with his finish sanding I will weld the plates back in and then return them to the plater for final plating. Here are a few pics.

Would love to hear more about your background in this type of work.John, Thanks for the complement. I have been around cars my whole life but only as a hobby. I am just a regular do it your self kind of guy that is pretty handy. And I do like tools. I finished up a restoration on a 1961 Bel Air Sport Coupe in August of 2011 and was looking for a new project. I was looking for a 54-57 Olds or Buick when this car crossed my path. I brought it home on January 10, 2012. I decided I wanted to use the 57 olds dash in this car so kept my eyes peeled for a dash and even comunicated with some of the other members here that had 57' Olds parts. I managed to find a couple of parts cars this past Spring and was able to disect the dash out of one and then install it into the Super. I also chose to use the Olds steering column and wheel. I also used a brake peddal assembly out of my 60' buick parts car. The back seat I am using is from a 62' Olds Starfire and then buckets out of a 64' Grand Prix. I also have a split bench seat out of a 55' Cadillac but I have not yet picked it up so I will decide once I have it what front seats I will use. Of course these will all be recovered to match. Here are a few more pics of my progress. Link to comment Share on other sites More sharing options...

421-6speed Posted November 6, 2012 Author Share Posted November 6, 2012 Here are a few pics of the modification I made to the steering column. In order to clear the exhaust manifold I had to flip the shift dog around and extend it 1-1/2". I pulled the shift tube out drilled out the spot welds on the shift dog cut the sift dog off at the Z bend then welded on the 1-1/2" longer arm slipped it back on and plug welded the dog back on. Notice I am using a 401/425 exhaust manifold...I also cut 1-1/2" off the end of the column tube then cut the coupler off the end of the steering shaft to make room for the new Bogeson U-joint. Then I machined a new end piece using a roller bearing to support the steering shaft and shift tube. I also used a rubber dampend Borgeson U-Joint at the rack.

Please keep posting updates, I would love to see this car finished...John, my plan is to put a windshield and back glass in, install the newly rebuilt 425, and make it road worthy. Then drive it this summer working out the bugs. No side glass or door panels just the bare bones, front and rear seats. Then next winter tear it down for paint and upholstery. When I bought it last January I figured it to be a three year project. Link to comment Share on other sites More sharing options...
421-6speed Posted November 14, 2012 Author Share Posted November 14, 2012 I bought a set of Ed Miller C4-C5 caliper brackets so I could install my C5 Zo6 Rotors and Calipers. I was a little disappointed in the bracket. I could have made these myself but decided to buy them as his site said included all hardware and figured it would save me some running around as I don't stock Metric Fasteners. The abutment brackets that mount to the spindle use a 14-2 mm bolt. Ed tapped the bracket for a 12mm bolt and then supplied 12-1.25mm bolts. Well needless to say that was a sloppy fit and I was not to happy so I drilled out the brackets to 9/16" then used the stock abutment bracket bolts from the C4 and bought four 14-2mm nuts. Then set everything up and tacked the nuts to the brackets. What should have taken me fifteen minutes ended up taking half a day by the time I ran into town...All in all it did turn out good. Here are few pics. Link to comment Share on other sites More sharing options...
421-6speed Posted November 18, 2012 Author Share Posted November 18, 2012 Got the bumper ends back yesterday in copper. Welded the plates back in with the new shields I made to seal up the bumper ends from exhaust. Now I have to block out the copper to 220 then take them back to the plater for final chrome.

I know that some disc brakes will fit 15" wheels but I can't tell you if they will fit your stock wheels. That would be a question for the manufacture of the disc brake assembly. The tires and wheel I am running are 18's & 20's. Link to comment Share on other sites More sharing options...
421-6speed Posted November 18, 2012 Author Share Posted November 18, 2012 I got the bumper ends blocked out today. I took them down with 220 then hit them with 320 and then hit the edges and a quick once over with 600. Link to comment Share on other sites More sharing options...
smithbrother Posted November 19, 2012 Share Posted November 19, 2012 Just wondering why you didn't use the Vette front cross member? Did you not like the width it would have given you. I did the same switch, but used the Vette cross member, and saved a lot of time and money, NOT PICKING ON YOU, just wondered. Looking good for sure.

Dale in IndyDale, I considered using the stock crossmember but I think the Flat Out cross made a cleaner install. What car did you make the switch on? I would love to see some pics. Did you use the stock mono leaf spring or make the brackets for the coilovers or bags? Link to comment Share on other sites More sharing options...

421-6speed Posted November 22, 2012 Author Share Posted November 22, 2012 I have been working on my front end. The chrome on my grill looked pretty good so I thought I would polish it and see if it really was okay or need to be rechromed. As it turned out it is in absolutely beautiful condition.... But what a pain getting in between all the vertical bars.... I got it pretty good for now but it is going to take a little more work to get the rest of 56 years of dirt off. I have a couple of questions though. I have 2-pieces I can't figure out where they go (see pic), and then what does the top outside ends of the grill attach to (See Pic)?

What is your rear end ratio? also, going carb or fuel injection?I have not made my mind up on the rear ratio yet. I have every gear set that was manufactured for the 9.3 though. 2:56, 2:69, 2:87, 3:08, 3:23 & 3:42. I need to do some calculations with tire size. I am running a Elco 3X2.I recently read your thread on your Skylark. I like what your doing as well. Very cool car...

Guest 54fins Posted December 4, 2012 Share Posted December 4, 2012 ah, 3 deuces. I have the 425/400 drive train. Just my opinion, but I want highway ratios and an overdrive is expensive. The 256 ratio would be awesome, although you may not be able to smoke the tires Wow, I have a 84 C4 vette so I'm debating the front end. The C4 is perfect width, but the 57 is a little wider than a 54. The 57 is also lower, It's a very cool car by any standards. Nice to see someone do it, then I can anticipate the issues.

Nice to see someone do it, then I can anticipate the issues.I am kind of leaning toward the 2:56's or 2:87's. Russ Martin thinks I need to use the 3:42's but like you I am thinking "Highway", mileage and ease on the engine. I am running a 30" tire so I may be able to go to one of the lower gear sets. Idealy I would like to be under 2000rpm @ 60mpr. The front tracking width on the C4 is 59-1/2" and so is the 57' Buick. What is the front tracking width on the 54' Buick?

421-6speed Posted December 5, 2012 Author Share Posted December 5, 2012 I just went over to Richmond Gear and used their calculator. RICHMOND Street Performance CalculatorIWith a 30" tire if I use the 2:56's @ 60mph 1720rpm, 2:87's @60mpr 1928rpm, 308's @60mpr 2069rpm and 3:42's @ 60mph 2300rpm. I need to do some research and see what the 1st and 2nd gear ratio is on the 66' sp400. Anyone know? Link to comment Share on other sites More sharing options...
Guest 54fins Posted December 5, 2012 Share Posted December 5, 2012 I believe the track width is about the same on the 54, 59-60". The 57 body is wider, might just have a little more pot belly. The 57 is lower and sleeker. The C4 stuff is perfect. I like the rear end, and it has a 2.75 ratio but I also want to keep the car looking as stock as possible, so a straight axle in the back is easier anyhow. However, I'm more into highway cruising than street racing so I really don't care about the low end. Compared to a dynaflow it will be a huge improvement. Also thinking about fuel injection. For now I have to settle up on the frame. Would like to keep it all old school Buick stuff. The 57 buick stuff is heavy, but I like the engineering. The C4 is a very nice package but I have a ton of bumpers and front clip, It's just not going to handle like a BMW. Link to comment Share on other sites More sharing options...
421-6speed Posted December 17, 2012 Author Share Posted December 17, 2012 I'm headed to the chrome shop in the morning. Picking up a bunch of stuff that is in copper and ready for me to block out. Then dropping off my rear bumper parts ready for final plating along with the rear taillight housings and front bumper ends that I will get back in copper. Here is the center section all blocked in 320. I think the final product is going to look great... Link to comment Share on other sites More sharing options...
