Default 5.3 to 383

im building a 383, ive got my rotating assembly on the way, i plan on spraying the **** out of this engine, like a 250 to 300 shot, im expecting 500 whp before the shot. this is using my aluminum block. my question is... would i be better off using a 5.3 block? not worried about the weight, just the strength, any help would be apprieciated

The LS1 block will work just fine.

Yes, the aluminum block will do and if you dont want to buy one and already have a 5.3 block it can go 3.905- seen quite a few of em done that way.
