I'm new to the LS1 world and am starting to build a stroker LS1. I was wondering which of the stock cranks has a 4" stroke. I was planning on using a stock crank and forged rods and pistons for my build up, and after doing some reading here it would seem that the stock cranks are a pretty stout piece.

Any input here would be appreciated.

Thanks.

 

None,
4.00 cranks are aftermarket.
Stock LS1/LS6/Lq4/Lq9/LS2 are 3.622

 

^correct if your looking for a budget build, get an Eagle crank.

 

Ok...Thanks guys. I wasn't sure.

 

Just make sure you have a machine shop go over the whole assembly measurements and balancing.

 

Yeah...having somebody go over it and balance it brings up another question... has anyone had any problems balancing an Eagle crank? Are they a pain or realatively no problems?
