COMP Cams Dyno Results for XE274H Chevrolet 350 Small Block Camshaft
You have better heads and more cubes so id say 410-425ish if tuned right.
Peak HP around 5300-5500 peak torque 3000-3300.
This is my guess.

Sounds about right I know my heads are a little on the small side I'd love to pick up a better set maybe two tens but then again I've just got a GM crank so not sure I want to spend it any higher than 6000 RPM
I'd throw a guess of upper 300's-400 HP. My old combo was somewhat similar to yours and ran pretty decent for what it was:
-408 c.i.
-stock heads (ported and polished)
-1.6 stamped rockers
-comp 280H hydraulic cam
-flat top pistons
-dual plan air gap intake
-750 mighty demon carb
i had a TH350 with a 2800-3200 stall, which stalled in the upper portion of that range, a 4.10 gear (8.5 rear end with a spool), and it ran 11.7's in the 1/4 mile. I drove it on the street for a very short period of time, before making it a bracket only car. I don't think I'd want to be on the highway too long with the 4.10 gear. It was a pretty fun combo, and it sounds like you have something similar.
