Hey guys,

I'm gonna get my 302 back from the machine shop pretty soon. It's gonna be bored 30 over and it's getting all new shiz, forged pistons, the works. What should I do with it? Take the poll!!!

what compression..whgats the rest of your motor look liek and how much do you want to spend

compression is about 9.75:1, it's nothing major, stock rods, stock crank, forged pistons, GT40P heads, Comp cams 292H .534 lift, Weiand stealth intake, holley 700cfm carb, 1 3/4 long tubes, 2.5 off road H, 40 series flows, T5 , 4.10's, the car is an 84 hatch, stripped down to nothing. Tell me what yall think!

I voted for Nitrous. The main reason I did so was because your compression is kind of high for boost really. It's most ideal, especially on a stock 302 block, to run your base compression at 8.5:1 for a boosted application. ~9.0:1 is ok, but it depends on the amount of HP and cylinder pressure you're going to make with the amount of boost you'll be running. The stock 302 has serious issues with block flex and head bolt strength with high cylinder pressures and HP. If it were me, based on what you built, I'd set the mill up with a 150 shot of spray with a progressive rate controller of some type and RPM switches for extra saftey (2500 / 6000).
