A 383 can have 290hp and way up depending how its built.But for the price of you can get a used truck 4.8/5.3 with the trans.

I've heard that since I was a kid.
I think back in the day it probably had a lot of truth with limited custom parts but now I think its up to the builders ability. My family and I have had two top shop competition engines not winner's but a runner up once. if that counts for anything. Now days your ability to build horse power is limited to your ability to write checks.

This.

Believe me, I still love old school iron, but today LS stuff has become so comparable in price it's almost a no brainer. You can find 5.3's and 6.0's for almost dirt cheap. Throw a small cam in there, some custom tuning to disable GM's torque management and abuse modes, hook it up to a 4l60/80, and you'll be a happy camper.

In the GM platform LS series truly are king. And for so many good reasons.

tI agree -- here is not replacement for displacement, but with technology today, a 283 can easily hit horsepower levels only attainable by large small blocks form the sixties.
