i have a 302 and need some to decide on what to build. I have to bore the case .010 over to get some marks out and was wondering if i should go bigger? This motor will be on the back of a dunebuggy and will see action about once a week maybe. I am going to run AFR 165 non-emission heads w/ 61cc chambers. Edelbrock intake and carb any clue what size carb. I will run a bigger cam but don't know what size or anything like that; i want to have to down grunt to turn 36 inch tires but i also dont want the motor to crap out to soon. Roller rockers and just the water pump and alt. Any suggestions comments or anything would be great thanks for the help.

 

if the block cleaned up nice at 10 over, i'd leave it alone there. the max "recomended" overbore is .030. as for a carb i'd go with an edelbrock 600. don't need much more on a 302 unless you go wild. have one on mine and i love it. as for a cam summit part number crn-130052, crane cam has 216 deg int/exh duration and .484" lift. seems to have plenty of power down low, but doesn't stop pulling too quick either.

 

thanks for the info.
