I went to the dyno last night and I am pulling a vacuum at WOT. 3to5 inches. I now have a 850 holley with the choke horn milled. I called Barry Grant they said there 850 out flows a holley hands down. they said there 750 would out flow my holley 850. The guy that runs the shop were I dynoed said he would try a Migty Demon, he has had good luck with them. Does anybody run one what are some of the carbs you guys are running. I just hate to drop $500.00 and it do the same. I would think the BG carb would act better driving around town. To see my specs and dyno #'s go to the Sbject DYNO Help.

I am running the 750 mighty demon on a 355 it runs awsome. I had that same carb on a 496 it also ran awsome. I did jetting in both cases. I did have my share of problems when I first got the carb read some of my post's. Both motors were mild street strip.
