people with 5.3 heads....hp and et's????
i'm gonna be buying a set of heads soon. i will be going all motor so i want my compression as high as i can get it. what kind of numbers are ya'll pulling on the dyno. also what kind of track times. please list you mods and where you got your heads from. thanks
ive got 5.3 TEA heads arriving this week hopefully... i justgot them cause they have to mill them only .015 to achieve a 11:1 CR. Plus the fact that they are brand new never been run heads
