I will probably not use the car as a daily driver (for long)and i will probably take it to the track every couple weeks, But it WILL be driven on the street every once in a while but i won't worry about that.
I am hoping to have .035-.040" Quench and enough compression for the cam i get, and i can't use a steel shim gesket if i use the aluminum heads, but i like them better than the fuelie heads because i can run more compression and they have a more efficient combustion chamber, Oh yeah and they're ALUMINUM!!!.
I would rather not run race gas but i may have to.
So what heads and cam (any solid flat tappet) should i get and do the parts i am getting sound good or bad. any suggestions?
Very confused at what to buy!Last edited by zwuvlu; 05-09-2009 at 08:53 PM.
We managed to get a couple of other small things taken care of. One was blacking out the front of the core support. When the sun hit the front of the car just right that green paint on the core...
