~450hp from stock stroke 340?

My best friend in high school had a 67 Z28 with a 302 4spd 4.56 , that car would rev to the moon, did fairly well for what it was.
But no match for my 67 fastback with 383 torqueflite 4.57 .
i have a client with a 67 RS Z28 302/4spd, which i understand is crazy rare. it's a super time capsule and a really cool car. total day two with keystone kustomags, lake wood slappers and hooker's. i don't know if it came with 4.11's or the PO did them along with the other stuff, but it was a serious piece. the guy had me swap in some 3.55's so he could drive it and enjoy it a little more.

but to your point, that thing loves some gear. so much fun to twist its tail and just let it sing.
