Well, here it is....

With the 770 carb, it made a best hp 459 at 5500 rpm and 485 tq at 4500 rpm.

With the 950hp, it made 470 hp at 5500 and 505 tq at 4200 rpm.

Here is a video of the last dyno pull.

Thanks Brian, Mrs G-bob loves it.



Good to hear Glenn! Thank you!!
I will say that the 950 was actually jetted perfect for this engine, we had average 12.75:1 and it was in the low 13's at top end of the pull.

The 950HP carb was worth 20ft.lbs. of TQ!! Average HP gain with that carb was 15HP from 3000-5700rpm.
Average TQ gain was 20ft.lbs. from 3000-5700 rpm.
It idled down nice at 850rpm, nice chop to the idle and was clean and crisp even with the 770 Avenger carb.
Now it's time to move on to the other project....
