Anybody out there have any experience running a cast crank in a late model with a 750 4 bbl on alky. I've heard if you use synthetic oil and keep it under 7300 RPM, you'll be ok. Thanks

ditto running in mod 7200 rpms balanced though. i was told by a machine shot that the more weight thats hanging on the crank ie flywheel and balance the better chance it has of lasting. though i run a dd glide and stock 400 balancer and flexplate. likewise knock on wood.
