There are some casting marks that will let you identify them. Better alloy of cast iron, four-bolt mains, and six additional head bolts are big differences. Stage I was same casting, without the extra machine work.

Getting ready to build a engine and don't want to make mistakes in parts. I have decided I want the horsepower somewhere around 450-500. I talked to TA Performance this morning. I just want the right parts going in the engine so I don't have to go back and upgrade. Any help is greatly appreciated.

TA performance is def the way to go with thier aluminum block, but they only make them in short castings so you have to find out if there casting at the moment, or if they have any. you might want to consider going with a on center block, to reduce your piston drag, but im not really an expert on that.

The stock block can handle that type of horsepower no need for a stage if your HP is going to be 500 IMO.
I agree- no need to get involved in extra machine work, and hard-to-find parts, if you just want the power. The Stage II would be nice to have, though, if you don't mind the extra $$, and would be more "bullet proof" than the stock block.

When getting started, keep standard bore? What type of crank, rods, pistons when shottin for 400-500 horsepower. How about main bearings, rod bearings. Thanks for getting me educated guys!!!!!!!!!!

Stock rods and crank? Really. What do you guys think are the best pistons. I don't want to bore the block either, Right?

I'm making 450HP in track trim on a bone stock engine. Only external bolt on's and a bullet proof tranny.

With a steel crank, forged pistons, and good rods, 500 hp should not be a problem. The block is not the weak link, so much as the tranny. Once you start pushing over 350hp consistently, the tranny will need some attention.

Any of the reputable tranny vendors we have can make your present tranny hold up to way more than 500hp. The right use of billet parts will pretty much bullet proof them up to the 500 hp level. Try as I may, I've never been able to break mine since it's rebuild replacing the weak parts with billet pieces.

I had mine done by Don Wang out in Southern CA when I was living in San Diego. He used some good clutches that he's familiar with, and several of the hard parts were replaced with Bruce Toelle (performance transmisions of Sacramento) billet parts.
