Hmm, I would say 445 to 455 HP. I admit that my 383 solid roller just made a little bit more.. 612 hp with dyno sheet. It is a little more radical than your build, but I had another 383 that had similar specs and it made around 455 hp on the dyno.

The dyno in my head says 450 hp

I'm guessing in the mid 400's. That is really low compression for that engine setup.
Are you using dished pistons to get compression that low? With flattop pistons your comrpession should be in the mid 10's1971 Camaro, 383 stroker ~500HP,M21 Trans with lightened flywheel. All Sorts of Auto-x Goodness in the Suspension. 12" Brakes ->SOLD
But ask me about my 2004 STi Auto-x car...
Just call me Brett

-18cc pistons are used, but the compression is a unknown for me because the engine block has been machined and i dont know by how much. The smallest number possible is 9.7 my is guess: 9.8 - 9.9All under 6.27 litres is a starter.
