pinto????????
my pinto was built in 1981--all original parts are still there excepting rings-bearings-cam.
it has seen lots of missed shifts and several 1-2-1(should be 3)that resulted in revs close to 10thou.it is still a strong natl engine.

just for fun we have a wrecking yard motor that we shaved the block to get 10to1 with a big valve head-big cam-twin 45mm side drafts.
we abuse the #%$@ out of this thing for 5 years in a s-2 and its still good.

i dont think a pinto head will flow enough to hurt it self.
if some one is breaking pintos they need an engine builder!
no shortage here--picked up 5 good cores in last few years.
