I am planning on doing a rebuild for my 383, I want a mild motor w/ about 425 HP, I think this will do it.

383 w/ steel crank and '71 oem rods
Rebuild kit from summit, flat top pistons
.030 over bore gives me 389 cubes

Hard bloc in the water jackets, Hi Po Mopar mag says that is worth 20 HP

about 9.4-9.7 CR

'516s w/ 2.08/1.74 valves, bowl porting
Port matched Performer or Weiand Action + intake
3310 Holley 750 cfm Vacuum secondaries

Comp 270H "K" cam kit advanced 2 degrees
1.5 roller tip rockers
Align honed cam bearings and bores, Maurice Petty says it is worth 15 HP

1 3/4 Hedman hedders w/ Jet Hot inside and out
2 1/2 in exhuast w/ balance tube

Rebuilt Electronic distributor and chrome ECU

727 TorqueFlite w/ 2500 stall B&M Shift Kit, low 2.74 first gear


3.73s and Detroit locker in an 8 3/4 case

3800 lb car race weight

What do you guys think a car like this would run?

Comp 270H hasduration of 270, dur @ 50 is .224, lift is .470, 110 centerline
