Need help on building a 4.3 up. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

First off, not mine, my buddy has a '87 Blazer with a little TB 4.3 with auto. I have seen these things built up, and remember one, but that was like 6 years ago. He doesn't want a 5.7 swap, and just wants things to make it a little more powerful. Maybe a cam, headers, and maybe swap it to a carb, or something. I'm lost, at where to get anything, and what to do.

Far as I know, its basically a 5.7 minus 2 pistons. I'm sure there is a lot more. Can anyone help me?
