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

 

you've got me bro. I don't have a clue, but i'm interested in this as well.

 

can anyone help me here? im sorry if this has been brought up before, i searched for awhile and didnt find anything that directly, or remotely for that matter applied to me...

 

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.

 

thanks guys,
