Y'all have obviously never driven a Pinto with a 351 Windsor V8 swap in it. Now that's a fun time! Especially when the rear hatch starts to leak in the rain because the body is so twisted out of shape. But as for the stock Pinto motors, didn't they crack cylinder heads on a regular basis? I remember that the sleeved Chevy Vega blocks failed horribly, but the Pintos were actually not too bad except for the cylinder head thing, weren't they?
Either way, welcome to the site!
