Exactly why I did this. A big weight was lifted off me that nothing broke lol.

Yeah pretty much out of the box. We didn't even do a jet change. Just adjusted the 4 corner screws. I bought a QFT 1050 originally. When talking to Dwayne over the phone he said it was too big. So I bought the 950 body and swapped it. I plugged the emulsion so 2 out of 5 are blocked though. I think it's botom, middle and top open like a old school holley double pumper. The cruise test on the dyno under light load showed it considerably richer in the 10.3 2900 rpm to 11.7 range 3000. So a afr gauge in the car will need to be used and much more learning lol.


Nice numbers for sure but don't agree that the 1000 would be too big w/that power and I put Dommy's on motors w/less that pick up a LOT of power...........All in the tune and I also like to be richer in the high load areas like leaving the line and mid range then go slightly leaner up top...........A skirted big bore 1050 Dommy would wake that puppy up............ thumbs beer


He said a 4150 1050 might make it sluggish on the street. Wouldn't give up power though. But yeah. When I step it up in the future. If I go to a 1050..It'll be a dominator. I'm sure I'll be wanting to get a hold of you when I get the car ready and sorted with a afr gauge with this carb to get a good start suggestion. I read all your posts and have for years on here. I love your car too.
