Got this info off another site and it was just off the dyno cause I know alot of people are trying to make ecinomical power these days... I must say I like the numbers... 501 HP and only 32* of timing..... I know alot of you are considering this so here is your foundation... now fully port these heads.... and add a bigger cam
looks like a real good reliable combo

I will list parts and then dyno numbers.
