So, a drag racer friend of mine was going to let me use the build sheet from one of his old racing 289's, and I was wondering what heads I could use that are equivalent to the worked over '69 351w castings he used...
So I don't have the sheet yet, but he mentioned 12.5:1 comp ratio, .690 ish intake and .700 ish exh lift on the cam, Forged pistons, stock rods and crank (balanced of course), and a few other things that I can't remember exactly. Either way it pushed his 65 mustang into, I think mid 6's in the 1/8 mile.
So, from what I gathered you would need to spin the 289 7500ish to make that kind of power... So what kind of casting could I pick up and or clean up on my own to feed a .030 over 289 to 7500+? I thought gt40 heads, cleaned up, but what else would work?
