How can you compare this build to other cars?

A quick method is to measure the weight to power ratio ( lower is better)

Weight/Power Ratio:

Car Model:
Nova + 383
2900 lb
Z06 Vette
3200 lb


We are going to show you exactly how we build this car. From when we picked it up as a used car, to when we put the final screw in it and took it to it's first show.

When we bought this project car, it was a running car, kind of. The engine needed to be tuned and adjusted and most of the interior was removed including the stock dash, carpet, rear seats, and more. The rear suspension really needed help, and the body needs a lot of work.

This isn't a bad project car though. The engine and transmission are good. We made some adjustments to the timing curve, timing advance, idle mix, and other small adjustments here and there, and the engine runs like a beast. We will have dyno numbers soon. The engine actually only has about 1000 miles on it. There is a lot of slack in the rear end though, so we are going to show you how to fix that, as well as other components of the rear axle and suspension soon.
