Jumping compression from 9.0:1 to the 10.5-10.7:1 neighborhood on a 351C will net around how much power? Nothing else changes... moving from 2V heads to Aussie heads. I am just wanting to know if I should bother with the head rebuild now or shelf them until I get ready to do the whole engine. The shortblock is sound, I jsut dont wanan pop off the export brace for next to nothing in HP gains.

Also, how would a stock 2V Cleveland compare to a 1991 5.0? Talking flywheel HP here. I know there was a change in methodology concerning the measurement of HP, I jsut have no idea what it did to the numbers.

Yeah, that's a conservative number. I went from 9.5 to 13 to 1 in my 466 & picked up almost .7 in the quarter. It's a good way to make more power

According to my Engine analyzer, the 2V Aussie heads (ported) are worth about 70 HP on my engine. Make sure you have a cam that will bleed low rpm cylinder pressure. With 10.5 compression, you will be in the "knock zone"
