SCAT superlight crank
I run a 440Source 505 stroker kit with their ultralight crank. It was advertised at around 5 or 6 lbs lighter than the normal crank they sell. It's in a stock 440 block, aluminum main caps, ARP main studs and a 440Source main girdle. My line of thought was that with the stock block the less rotating weight the better. 2 seasons on it now, 12.8 CR and 112 octane, works well.
Initially had a leaking rear seal on the dyno, replaced the seal and clocked it at 6 & 12 oclock position, no further leaks. Using the stock seal retainer, did have to do a little clearancing on it I recall.
