Has anyone maid a ls 6.0 iron block into a 421ci for boost I have the block bored .030 and have a 4.125 crank and 6.125 rods and custom pistons maid for it with a 106mm turbo. Been reading and seen where people are saying going to have oil problems and it's not recommended for boost. And now I'm second guessing my build. Any info will help I really don't want to go a different route cuz I've done spent a lot of money. Sorry if my spelling is bad..
