347 Hp Estimate?

You're going to need all of that and a lot of compression to get 450rwhp out of a 347. 450rwhp is a tall order. You can get to around 375-400 with just a better intake and a 205cc head and reuse your cam etc. It should peak in the 6-6300rpm range. If you're going to make a max effort stock block that's the direction I would use. If you went the solid cam/shaft rockers-225cc head, you would have to shift that at a very high rpm(72-7500+rpm). Stock blocks do not like high rpms and will eventually break.

You could just throw a small nitrous kit on and make 450 easy.

The girdle on my stroker is so that, maybe, when my block splits I might be able to save the rotating assembly. Still wish I would've built a SHP block but..... you live and learn.
