My car already has floor mods, no #s engine, etc. It's up to you, it's your car. Looking at what you want from it, and seeing your knowledge of what needs to happen with it, I'm kind of perplexed at why you'd want to use a whole car anyway. Why not just park it, find a unibody shell with a good roof and A pillars, and go from there? I've seen them go for a couple thousand. You want have nearly the work cutting and storing aprts, and you can build a safe, powerful race car. You know how a back 1/2 car runs. They stand up. A full tubular frame, glass nose, engine set back, and 4 link will run killer numbers with minimal power, because it's so much lighter. A friend did this with a '73 CHallenger. With an all iron 440, 3 link, and steel 1/4s, he runs low 10s at 2700lbs with him in it. That's a simpe solid cam ported 906 head engine that spins 6K. With a factory cowl and firewall, you'd have to cut all that out. Tubular's the way to go. Keep your investment in mothballs. It's hurting nothing sitting there. Just seems to me it's the worse of both things. It's a real U code car, and it would never be as good a bracket car as a true purpose built race chassis would, for similar cash. Car looks good now. Is there a reason you dont want to race a 10.5 type class? Those will safely run in the 10s..How fast is fast for you?
