The motor is a 77 440 with 9:1 compression, early 906 heads (milled a little to get the CR where it's at), a cast iron intake, .484 MP hydraulic, Hedman headers, MSD 6AL, 2,800 stall convertor, 3.55 gears, blah, blah....

Very mild build.

The intake will be replaced by Holley Street Dominator when I find a good used one.

I have the two carbs at my disposal and have always been happy running the 750 3310 on other similar combos. My experiance has been very good drivability and power for mild combo's.

Will the 850 Demon be too much?
