Short update. I have nearly completed installing a Detroit Speed Decalink rear suspension. Although it was designed for a C-2/C-3 Corvette, it was fairly easy to adapt to the C-1. Required a modified cross member, a hoop to support the front of the differential, and provisions for the 4 forward links. I will have Mark Williams build new forward links out of 1.25"/.095-wall Chrome Moly tubing to get a custom length and enough strength to handle big horsepower and big tires. The 345s on 12.5 inch wide Forgeline GA3Rs fit perfectly. The motor is done and waiting to go on the dyno. Hoping to get on track early Spring.

Finally got the motor on the dyno. 852.71 peak HP @ 7100 rpm, 685 peak torque @ 5900 rpm. Should be enough. 515 CI BBC, short stroke (3.875"), big bore (4.6").

Awesome! Would be cooler with a sound clip or two.

Here is the dyno sheet. The AFR was a little fat on this run and the timing was only at 34 degrees, so there should be a little more in the motor with tuning. I'll look at that when I get it installed and on the chassis dyno.

That's a nasty big block. This is going to be one wicked ride!! What transmission and gearing? Apologies if you mentioned it already.

Can't wait to hear how this thing works once you get it out on the track!!! Makes as much power as the 9.0 liter and maybe a little bit more.

Thanks. The transmission is a TKO 600 Extreme built by American Powertrain - treated gears, better syncros, .82 5th gear, good to 950 ft/lbs of torque. The rear is geared 3:73 (Detroit Speed Hammerhead) - a little low but good for the tracks around here. I'm anxious to get it on the track as well - some stiff and fun, friendly competition here in the desert. I'm giving up some of the nannies, but I believe the suspension is well designed, the car is light, the weight distribution is perfect, big tires and brakes, and the aero is pretty innovative. It's set up to convert to a sequential and traction control (Motec) if I have to, but I'd rather stay "old school" for now.

I am guessing it has a 1.21 3rd gear and 1.0 4th? How tall a tire will you run? 31/71 Michelin or a 325/705 Pirelli? Nice drag race down the front stretch at any of the tracks you guys frequent is definitely in order. Your car is going to pull harder!!

The car is technologically unique and exceptionally well done. The sound alone would be worth the price of admission to me. It will be brutally fast and an incredible amount of fun. Hope you get some great video of it in action!!

Default Update

A small update. I got my fuel cell from Fuel Safe - they did a nice job of building it to my spec and Scott at fuel Safe was on top of it all the way. FIA certified pro cell in a .063 aluminum can, powder coated with an internal Aeromotive A1000 pump. They built a nice trap door catch area (1.76 gal.) for road racing purposes. I followed Aeromotive's suggestion and added a Setrab fuel cooler to the return line. I got the Detroit Speed Decalink multi-link rear suspension installed which required a lot of body and frame fabrication (it wasn't designed for an old C-1 Corvette). I also bought Cable's (NASA Viper guy) trailer - he bought a bigger one to haul 2 Vipers - LOL. I have a Viper, so I guess the logos can stay. Goal is still to have it on track this fall.
