Sorry one of techinspector1's posts got split out by accident so here is a copy of what he posted. Hey Danny, keep your shirt on buddy. Sometimes I have other things to do, but when I get time, I'm always be pleased to run the DynoSim for you guys.

I'm gonna change some parts around, because foolin' with this toy for a while now, I've developed a feel for what works and what doesn't. I kept your heads, but changed the pistons to KB193. They make the same 9.6 SCR that the others you listed do, but the rings are 5/64" instead of 1/16". Better for a street motor. I also changed the cam to a little tamer model. The one you had listed wouldn't make enough cylinder pressure with the 9.6 SCR.

355 Chevy, 9.60:1 SCR w/KB193 12cc dish pistons
Patriot 195's w/64cc chambers
Performer RPM intake w/750 carb of your choice
CompCams XE274H (This is a flat tappet cam. Personally, I'd use a roller, but with these specs)
274/286, 230/236, 110, .519/.522 w/1.6 rockers, installed 1* retarded.

RPM HP TQ
2000 138 364
2500 177 371
3000 228 399
3500 289 434
4000 348 457
4500 402 470
5000 442 464
5500 470 449
6000 477 418
6500 459 371

Hey, 477/470 from a mild 355 is not to be sneezed at.
