| 1000-1300hp Without knowing any info, it's a complete crapshoot.

I mean you couldn't miss that by a 300HP spread  If done correctly 1200 isn't out of the question. I think a conservative figure is 1100-1125 on a more "mild" build. |

DRR Trophy
| As mentioned, depends on a lot of things. For reference, our 615 Dart 11* (untouched heads), Profiler intake, similar on compression and lift, with q15 fuel, one 1150 carb, made right at 1200.
Had Dart run their "D" program through them, went up to 16:1 compression and a cam to take advantage of the porting, and picked up 50 HP to be at 1250. This combo, with a Super Comp style converter (slow 1.03 60ft) at 1920 lbs has been 6.99 and almost 192 at 2000ft DA.
Based on what you said, if it doesn't make a minimum of 1200 I'd be disappointed (even on a tight dyno). |

Mine only made 1020 but it has conventional heads and less than .850 net lift. It’ll still run 8.90 at 180+ so it’s good enough for me considering the budget.

Assuming the heads are ported a well built 632 with those heads has the capability to make 1350 HP more or less with that compression and lift close to 1". Anything less than 1300 would be sub par IMO or the combo was just not built to utilize the full potential of those heads. |

Is this in a dragster? |
