Okay, so a friend of mine had an engine built and dynoed. This is basically what he has and what it put out....

========================================================
355cu in
road demon 625
GM L31 Vortec w/ 1.94/1.5valves
Edel Perf RPM Vortec
CompCams Xtreme Energy 268* hydraulic, 224/230* dur @ .050, 268*/280* dur, .477/.480lift (.508/.512 w/1.6:1 rockers)
ComPCams roller rockers 1.6:1
Hedman Elite 1 5/8 headers
SpeedPro dished pistons
Stock rods
Scat crank
Pertronix HEI dist
36* total timing
8.75:1 compression

390hp @ 6000rpm
426tq @ 4000rpm
=========================================================

After doing some research, I've been thinking about building a combo of my own. This is what it would be....

--------------------------------------------------
383 cu in
Speed Demon 850 w/ 1" open spacer
AFR 195 w/ 2.02/1.6 valves
Edelbrock Vic Jr intake
CompCams mech roller w/ .578/.584 lift (w/1.52:1 rockers), .242*/248* dur @ .050
CompCams ProMag roller rockers 1.52:1
1 3/4" headers
forged pistons
forged rods
forged crank
MSD dist & 6AL
35* timing
9.5:1/10:1 compression
---------------------------------------------------

I'm thinking my combo is good for 450 - 475 @ the crank naturally aspirated. Ofcourse if I decide to be budget minded, I was considering going with a setup like my friends only with a 383, think that'd get me 400 - 415 hp from that combo?

Any and all comments/suggestions welcome.
