New to V8's. 340 or 383?

What if I wanted 300hp instead of 275hp, is this a huge chunk of change? I know it costs money to go faster but I'm not wanting to build a race car here. I just want something that's comfortable to drive and can make me feel some G's every once in a while when I want to get on the pedal for fun.

I will admit I know nothing about building an engine so if/when the time comes for me to get it rebuilt, I will be solely depending on you guys for answers on what to do. I have a lot of researching to do but I'll by no means be an expert when the time comes to get work done..

I think a bit of cam and set of headers will get you to 300+ HP without a lot of $$ or fussing. (I've heard folks claim they were 300+ right off the show room floor..) And I know what you mean about just wanting a 340. I've had a hankering for one since I got my butt handed to me in my Nova 30 years ago by a Duster 340...took all them years to actually get one, but I never lost that desire to have one of my own. Just one of those things...
Look forward to following your build.
