Default 346 to 347

Well..my motor is fucked up, a rod is broken...I know someone who has an LS6 block with 20k on it they will sell me. I can get a 347 rotating assembly from texas-speed....Will all of the parts fit into a 346ci LS6 block?

now what about a 402 rotating assembly? Would I be able to fit a 402 rotating assembly into the LS6 block? How much would I need to bore the engine over? Would I need to re-sleeve it?

You could get a 383 stroker rotating assembly. You need a 6.0l with a stroker kit to go to 402ci. Resleaving a ls1 is not worth the money.

Ill take your word for it lol..I think what im going to do is build this LS6 block that someone has...and possibly put the LS6 heads on as well, and cam it..

My Plans:

Texas-Speed 347 Eagle Rotating Assembly
LS6 Block w/ LS6 heads
Cam (probably custom grind)


Hope for 380 rwhp through an auto


Things I already have: I havent put these on yet

Performabuilt Stage 2 4L60-E
Yank PT 4400
Pacesetter LT's and Y pipe (from texas-speed )
