Here is another parts list to build up your own GM crate engine for less that crate prices. I know the market is moving towards the LS as the new 350, but there are plenty of us out there who are more than happy with an old-school 350 under the hood. And if you are on a budget, notice how the part numbers for the block, crank, rods, and pistons don't change much. So, if you are looking for advice on where to start a budget build, focus on a stout short block. Then you can swap cams and heads later for more power when your wallet improves.
