Durability of a stroked 346 to 383 Any info on the Durability of a stroked 346 to a 383cu.? I know the ls1 has thin cylinder liners and was wondering if any of you 383 guys have had any problems. I know that extra stroke can't be any easier. If you don't have a 383 please don't post. I need 383 veterans only please!

My 383 was built in the summer of 07,and to date I have not experienced any durability (reliability) issues. Prior to purchasing my stroker kit from Eagle I had a discussion with one of their technical representatives. He advised me not to go any larger than a 4.00 stroke (crank) based on possible reliability issues down the the road with the larger crank (4.125).

I can't honestly recall what he actually said,but I think it was related to the angle of the rods coming off of the larger crank. Give Eagle a call and see what they say about the two cranks (4.00 vs 4.125) in a LS1/LS6 block.

I'm considering "freshening" up my 150,000 mi LS1 with a new rotating assembly and a hone/bore as needed. 383 is the most obvious option. I'm trying to figure out if I'll need to swap out my 228/232 112+4 .590 cam to work best with a stroker or if its a decent match. Any opinions? I already have PRC Stg 2 243's.
