Hey guys,

I need some advice on what would be the best pistons to use on a Darton sleeved LS1 430 w/ 4" stroke. I will be using unmilled LS7 heads with factory valves and upgraded springs. I want the most power for a N/A setup. Currently the shortblock has -26cc JE forged pistons for boost and I need to get more compression for the N/A route. (these pistons will be for sale shortly) What would be the ideal piston - brand and top configuration?

Thanks,
Jeff

diamond, je, manley...all make great pistons. just get a flattop with valve reliefs and do the math for the comp ratio

racecar

I've had good luck with JE.

From what you have told us Mahle has a -4 shelf piston that will give you ~11:1.
