I'm building a chevy 350 for the 57 pickup. Have a set of 291 double-humps, but are not rebuildable. I see I can buy Vortec cast iron (64cc) at Jegs for $290 each. I'm using flat top pistons and am reaching for a 10:1 ratio.
I know I will have to get a Vortec intake, but is that the only difference? Still use the same stock length pushrods? Have to use self-alligning rockers? If so what are self-alligning rockers??
Vortec seems to be an inexpensive way to go. Thoughts are welcome...
