Then I read the rest of the thread and got to thinking. Sell the entire thing and it'll more than finance a B block 383 or 400 stock stroke so you can wind the **** out of it for autocross and 833 trans for some compression braking. Throw on some aluminum heads and intake to kick the weight down, fiberglas hood, fenders, valence and bumper, and your front end will end up lighter than a stock LA engine front end.
There's the start of your autocross car. Since you're going to throw it in a dart, why not something like a 64 dart wagon for your autocross toy? Make up a set of plastic groceries to fill the back too. The idea is to beat AND humiliate all those kids in their riceburners with the fart cann mufflers...
