Hi everyone, currently I have a 350 in my 82' C10. The engine runs strong but is starting to leak and needs all the gaskets changed. While it's apart I'm going to beef it up somewhat and have a decent street/strip engine. I was thinking 355 or buy a 400 block, since the 383's are extremely common here in my town and I want to be a bit different and still have something I can take pride in and say " I built that!". I'm looking for 450 hp and still have decent street-ability. Thanks!
