Have a 455 olds in my boat. Recently had issues with it. Pulled engine. Had broken rings and some cylinder wall damage from the rings being bad.
Question is machine shop says the crank may be no good because of the nitrate would be removed if needs machining. Is this wise to do or get a stock good crank and just polish it?
Crazy thinking says switch to bbc. Which I would love to do. Any place I can buy all the mounting, bellhousing, flywheel, driveline and such?
Thanks
James
