I'm working on my LS! 5.7 346 engine and I'm kinda struggling about what to choose for the forged pistons and rods. sizes and compression would also help.

my target is 800+hp

please advise!!!

799 and below- keep it stock.

800+anything is better than stock Just mind your bore-your only get one shot there!

salemech

great! do you have any info about what compression to use. is 8.7 too low. what kind of rods to use.

9.5 on pump, compstar rods are a great value, lots of good Pistons out there, diamond, je, weisco ect. If it's apart now put good stuff in it and forget about it

salemech

cool man. well the engine is not apart at the moment. it's going to be on a 350z (Drift car) the car will be going sometime next week for the cage, tubing the front and rear end. while the car sits at the fabrication shop. I'm gonna work on the engine.

What kind of rpm?

salemech

maybe 6600-6900. haven't thought of it yet or asked anyone yet. do you have any idea

I don't know the first thing about drifting other than the cars that do it tend to turn very high rpm. That may influence how you build the motor

salemech

well they go somewhere close from that but they really have some good double valve springs and retainers since they almost rev all the way for like 2 minutes till they finish the lap.

check this guy out here. 800 & 1100nm turbo.
