I ran a tunnel ram with 2 660's on a 396, not fun to do a jet change, huh!
It went faster with a single 850.
Before Holley offered a competition line of carbs, I made a few bucks converting double pumpers to 4 corner idle carbs.
I used to laugh when I could get even the most radical cammed engine to idle around 750 rpm!
Had a 83 Mustang Gt with a factory Holley that never idled properly.
This carb had secondary idle adjustment screws that were in the throttle body. All I had to do was remove the caps and presto.......4 corner idle adjustment!!
The f.e. dragster you had..............I understood the Crowerglide clutch part but, what's a "BJ 2 speed"?? Similar to a Lenco?
