I am in process of building a fully forged 355 bottomend,I know what rods and crank I am getting,but choosing the right pistons is what I need help with,I am buying the rotating assembley from advanced induction and their website says it comes with either -5cc (which I know I dont need)-16cc or -26cc,I need my C/R to be around 9-9.5,so what would everyone here recommend,btw I will be running around 12-20psi from a turbo,I am open to suggestions and I am also on the look out for a non-rear mount turbo system,any suggestions

oooo very nice! i dunno. as slow knows im a scat fan hahahahhaha but i think its all a mater of personal preferance maybe brand wise. as for the size id go for the -26cc's. should get it nice and low but not TOO low. or you could always go with the -16cc's and double gasket your heads

well i dont kno if these are the best, but what i run in my motor are a
JE/SRP forged pistons, and have a flat top with .050" dish cut into them. they have a total seal nitrous/forced induction styl ring set on them, but i have ALOT more compression.

what you will make with 20 lbs, on my stroker with 11plus to one compression motor will make with like 7-10 lbs.

you can make SAFE power with compression and tuning, and less boost, dont let anyone else tell you otherwise.
