Gm 383 hp crate engine
Has any forum member balance or had one of this engines blue printed? If so could you pls print improvements. How much more of a difference in HP/TQR was there. Any info will be appreciated. Trying to get all info I can before I buy one. TIA

Are you referring to the HT383? If so, from the line it really should be relatively close. It was intended as a truck drop in and never was intended to go into high power applications. I'm not sure how many other 383s GM offers so if there is a high output version this is news to me. Personally you'd be better off building your own to your desired application imo.

I'm referring to GM's 435 hp/445TQ it's HP 383 . Not the HT 383 truck engine. Hope that help's.

A cam change is the only thing you could really do. Can't imagine anything else would be necessary. I'd personally get a 1 piece rear seal block if this one doesn't have it.

Blueprinting will gain you very little hp. It helps with engine longevity and high rpm survival.
