- '79 CJ5, 258 I6, T150 w/Dana20, Dana30 front and AMC20 rear. My first Jeep! I'm looking forward to doing some minor upgrades and restoration while enjoying the ride.
Interesting but watch the Offy. I believe the design intent is that the primaries sit inboard and give advantage to low speed. The volume of the seperate planes are different and move air differently.
If your carb doesn't need that (sounds like the carb has atomization and low throttle beat in its design) I might consider a single plane intake manifold.
The Offy is not split between cylinders like you would expect on say a V8 application.
They are split on each cylinder for low and high throttle.
Not sure there is any advantage with an Offy on that carb. Not much anyway.
Different story when dealing with an old dogleg carb. There is a marked improvement in that application.
Not sure, as I said before, I am not familiar first hand with your carb.

I've been reading the Offy page about the DP manifold and i see what you were saying. I'll make sure it goes on correctly, thanks.
