I think you're right, I'll just stick with small stuff. I am on a bit of a budget so a turbo isn't the best choice.

and just keeping it running properly will help it run @ the top of it's game.
besides, if you've ever opened up one of these 4-3's you'd see that there really isn't a strong bottom end in there. cna make some half descent power, but you won't have a long living engine if you beat on it often.
about the only thing to strengthen the bottom end up is a marine crank. but from what i remember during my build, there were some mods needed to the block, and i didn't like what it was gonna do.
wanna increase the performance to what you alrady have? get rid of all the dead weight in the truck.
