Looking for a reliable rotating assembly for a supercharged 383 in the 5500-6000 power range. Looking for good assemblies that come from balancer to flexplate that come pre-balanced that will hold the power reliably for under $3000 and drop right in if thats possible. I have a 2 piece 4 bolt main block. Im going to run 76 cc heads and superram so I hope to have my compression around 8.3:1 which will hopefully allow me to run pump gas.
