I used a Scat rotating assembly. No matter what kit you buy take everything to the machine shop and have it checked and fitted to the block. EVERYTHING ! A "cruising" car does not matter, you want it right the first time and it will last a long time.
Why do you say that did your kit have a issue, reason i ask if i recently just got a kit and it was balanced by them. I sent the pistons with my machinist though
