All factory iron power
I recently came across an article from Hemings from around 2006 about a F.A.S.T. racer who built a 406 Cleveland with all factory iron parts (block, heads, intake, exhaust manifolds) and made 517 hp.
He was running 13:1 compression and though it didn’t give any specs on cam one photo showed what seemed to indicate solid or mechanical roller lifters. No information was given on what was done to the heads an intake.
It got me wondering what kind of power a person could make with factory 4v closed chamber heads, factory 4v intake, factory exhaust manifolds, and not more than 11:1 compression (hoping it would run on pump gas).
I wonder if 450 hp or more would be feasible with a 408 stroker and some head and intake manifold mods.
