Idk, CM.... This car is being built for the twisties, but it should hold its own in a straight line. This 400 is getting stroked, just gotta decide if I wanna go 433 and be able to rev it a little more or go 461.
Those heads will need a lot of work if you want to build more cubes and get the revs. They are corks. I have a couple of Tin Indian loving buddys and they gave up on the stock castings and went aluminum Edelbrocks.
I am just beating on you. But watch out................
