Engine builders welcome!!
Engine builders welcome!! I need some help deciding what pistons will work best in my new build. I have a LQ4 that is a 370ci motor. As of right now I have AFR 225's that have been milled to 70cc, Harland sharp adjustable rockers, 242/249 .610 .615 114 cam. My question is what pistons are recommended for my motor? Keep in mind I would like to be close to the 500rwhp (N/A) mark through my M6. The car will also have a direct port setup on it with a decent amount of nitrous. Thanks in advance!!
Are you sticking with 370ci or are you stroking it to 40Xci?
For a higher compression 370ci I'd look at the Wiseco +12cc dome pistons. With a GM MLS gasket they'll net you about 11.7:1 or so static compression which should be helpful in getting to your NA power goals. They come equipped with a steel top/napier 2nd ring set, coated skirts, radiused valve pockets to help ward off detonation, and more!

well I find out tomorrow what cc the heads really are. when I got them on trade I was told they were originally 72cc heads, after looking at them they look to be originally 65cc and milled close to 63cc. this will be a 370ci motor when done. what size piston do you suggest?

You need to know th etrue CCs of course first but you could use the pistons Matt is talking about and just cut the domes down to get what you want as they are solid domes. We do it all the time.
