into which we put a 429SCJ/460. In order to do this, and have the car handle, we cut out the firewall and set the engine back so that only the crank damper was in front of the original firewall line. We also put in a full frame and cage, a 9" Versailles axle, and then chopped the top by 4". The car weighed 2260 with an all-iron dummy engine and C-6. It had 1170 on the rear wheels and had the driver's seat on what had been the rear seat foot space. Interior laid out much like a corvette.

I note on re-reading the above that I may not have made things clear! It's possible (just) to put a 460 in a Pinto engine compartment. But all the engine weight sets right on the front wheels. This makes for lousy handling. Moving the engine back gives better access and much better weight distribution. KS
