Default Old Project Revitalized - 56 Track Car

I've been missing in action for a couple of years tracking an ACR and a Focus - got that out of my system. I'm not getting any younger so I decided I better get serious about finishing my old 56 Corvette track car that I have been "modifying" since 1975. I sold a couple of my old Corvettes for operating capital and I am devoting it all to finish the 56. So here's where I am. The car is caged, widened, and with a completed high travel/low roll front suspension. The rear suspension was a much modified C4-based system, but I was afraid it wouldn't be strong enough, so I just purchased a complete DecaLink from DSE with a hammerhead differential and 1200 HP axles. I am adapting the DecaLink to the C1 rear frame rails - should be fun. A couple of months ago I commissioned Larry's Engine and Marine (Tuscon AZ - renowned for their BBC offshore race boat motors) to build an all aluminum (Brodix) 515 CI big bore/short stroke (4.6 bore/3.875 stroke) motor with Calles crank/rods, 13:1 JE pistons, Comp Cams solid roller, TD shaft rockers, Dailey signature dry sump system, Hogan fabricated sequential injection intake system, and a Motec ECU. I just received my new Tilton bellhousing, rear mounted starter, and triple disk 7.25 inch carbon clutch. The transmission is a TKO 600 extreme built by American Powertrain that I have had for a while. I will post photos as things progress.

Didn't you have a watts link trailing link on your rear suspension? Always thought that was interesting.

Is that Tilton piece considered a scattershield? Or do you run a blanket around it? Whats the front suspension consist of?

The Tilton bell housing is legal for NASA and SCCA road racing with the carbon clutch. It is the same set-up that was used on the NASCAR COT - not sure about the drag racing sanctioning bodies. It also serves as the mid-plate with a Competition Engineering motor plate up front. The front suspension is a custom fabricated, high-travel/low-roll design with long fabricated chrome-moly control arms, JRI triple adjustable shocks/coilovers, and a Speedway Engineering sway bar. All pick-up points are on slugs for adjustability and it uses a Sweet front steer power rack with a Woodward steering column. The uprights are ATS with ZR1 hubs, Howe NASCAR-spec zero friction ball joints, and big StopTech brakes.

Very cool... wasnt aware that there are different specs for bellhousing/scattershields. Post some pictures of the front when you get a chance... Correct me if Im wrong but with that partsllist it sounds like youre drinking some of the Ron Sutton Kool-Aid too?

Yeah, Ron is a friend of mine and we have had many discussions about suspension design philosophy. We agree on most things, except perhaps the IRS. He prefers an offset three link. I buy parts from him, and I was going to use one of his Race Warrior LS motors, but I built the car for a BBC a long time ago and I had collected a ton of good big block parts - plus I just like the brute power of a BBC - so that's what I stuck with.

I have a couple of earlier threads here (56 Corvette and Adjustable Front Suspension) where I uploaded photos of the front suspension under construction. I tried, but was unable to reload those photos - guess that's not allowed.
