2 bbl. Motorcraft & a dwell cam

Bobby, Yes you read it right. Idle mixture screws are shut. There's fuel coming out of the boosters @ idle , but with the 1/4" holes in the plates & the idle turned all the way up, that's a lot of air going thru there. I don't THINK I have a leak but I'll re-check.

Sean, This carb is 350 cfm. I know round track 2bbl. Clevelands regularly go over 7k, with a 4412 Holley. A while back I ran this combo on a simulation program & no matter what I tried, power fell above 6K but I figured we don't race computer's & blew it off.

Bill C., About all I can say on reversion control is the cam has 40 degrees overlap @ .050 & a 3 angle valve job.

JMark, I found an article that has the same illustration & saved the file, thanks. I may just weld the advance in the dist. & set it @ 40. Anybody have starting issue's there ?

Thanks for all the input guys.
