well b17 is just like a b16 so all its hard to make it fast,but i would go with some Ctr "pct" pistons and tt retainers with itr valve springs.a set of itr or buddyclub cams a 10lb flywheel and nice street/strip clutch should make u alittle happier.....or sell the bottom end to someone who thinks its rare and buy a ls bottom it will make more power stock then a built b17 bottom
