thx guys I'm gonna try the CH28 2x4 with a pair of 600 eddy carbs.....its been mid 11s with the stock 6bbl 3.55s and stock vert. Great. Post your driving impressions and track results. It will be good to get real comparison data.

i use a ch28 on one of my 440's with two 600 edelbrocks. absolutely without any doubt in my mind the most street friendly reliable intake system i've ever run. i'd use 750's on a big engine or at least two 650avs2's. That setup looks perfect on the mopar440. In my opinion because of the mopars wide intake manifold I think dual under hood quads looks better on the 440 than the 454 and all other makes. Plus it pays homage to the days of more power mandating more carburetors.
Keep old mopars alive.

i have always wanted to try a ch28 with two 1 3/8" bore primary thermoquads. [800cfm ?] i know i would have to fab some offset adapters because the ones available would [i think] not allow the carbs to bolt on because they would hit each other. Offenhauser also still makes an under hood dual carb intake for the 440 with more carb spacing than the Edelbrock. But I have read the single plane Offenhauser is not as great a performer as the dual plane Edelbrock.

[quote=moparx]i But I have read the single plane Offenhauser is not as great a performer as the dual plane Edelbrock. Your correct on that Been there, done that The early Fire Power Hemi and inline dual quad wedge Mopar OEM motors came with single plane dual quad manifolds with progressive linkage, they flat suck compare to the stock 426 street Hemi motors with the dual plane intakes

I already have access to the eddy intake and carbs so its even more simple.....now what about an air grabber breather setup for 2x4?I believe spacing on the hemi is different correct?

hemi carbs are further apart. you'll probably to get a little creative. it may be possible to take the edelbrock air cleaner base and adapt it to a factory base. the manifold height for the ch28 is noticeably taller than a stock iron 4bbl, and i think about 1/2" taller than a ch4b but shorter than a ch6 or RPM intake. thx lew

Have you considered lowering the K member?

Lew any pix of your engine air cleaner setup?

Have you considered lowering the K member? that never crossed my mind. how much would be the max ? 1/2-3/4" ? That is the range. I usually go as much as the steering column or radiator shroud will let me. If it were possible to mount your carb without the adapter (or mill the intake down that same amount), combined with the 'K' drop, it would give you over an inch of extra clearance to the hood. I have an Indy intake and Dominator carb under the Shaker on my Cuda. Dropping the 'K', lowering the radiator, using a drop base air cleaner base, and modifying the air cleaner lid was the combo that made it possible. And you cannot tell it by looking at it.

Ive ran some smaller intakes on my 512. Streeter. It still ran like a bear. I went 10.95 with a ported six pack and 10.92 with a TM6 and a 4150/1050. I have a Indy single and a dominator on it currently and it feels stronger but, it’s gonna get the six pack when I put a 4 speed back in. The TM6 is surely one of my favorites for street duty.
