If im trying to put down around 900rwhp eventually with NO2 and maybe a blower will a LQ9 iron block be able to hold or should i go with the lsx.

Im currently running a 150 shot with the stock bottom end and PRC ls6 2.5 ported heads, a tsunami comp cam, LG lts and borla stingers and its at a little over 600rwhp. Any input is appreciated

 

Six speed car or auto. A LQ9 will hold the H.P I have buddies pushing 1250 on a 408 iron block. But you need to build it with the right internals.

 

Its a six speed(z06).. what would your suggestion be on pistons, rods, crank, ect...

 

I would just call LME or AES or Texas speed for your applications.

 

Those Iron blocks will hold up just fine for those power levels!
