Lucas,
You're doing the right thing by keeping the car original. There is no way you could update that chassis to be competitive in todays world of N/FC, you have to run 6.00's just to get qualified and usually 5.70's to win. The whole spirit of the class from the competition side has been ruined by the few that can outspend or out-tune the majority that have built N/FC's just for the dream of having and running one. The same thing happened earlier in the Nostalgia Top Fuel classes and now if you don't have a 78-79 Arrow, Firebird or the like, you don't have much chance of being competitive, so the guys that built the earlier 67-72 bodies are pretty much relegated to match racing or exhibition just to have a place to run. And since NHRA has seen that they can put on a show, they've stepped in with the Heritage Series since they can make money off of them and started slapping big show style rules,(carbon brakes, leahy boxes, etc.)driving a lot of the little guys out, which doesn't make sense, but we all know NHRA has a nasty habit of crapping on the little guys. Enough rant, keep posting and keep us filled in on the progress........
