you will need the ls crank, ls rods and pistons to fit the ls rods.

You just need proper spelling, punctuation and capitalization.

You shouldn't need any machining outside of standard block rebuild work- everything will drop right in if you get the correct bearing clearances between the crank and the journals in the block.

LS crank will fit in a GSR block, I've done it. Some machining is necessary.

LS rod length is a must. You don't need stock LS rods, in fact, I recommend aftermarket because the factory rod bolts are crap past 8k.

Pistons - Choose any B-series you like. I ran JDM ITR .25 overs and achieved 11.8:1 CR.

But, you can go bigger if you like.

Enjoy the extra torque!
