OK. Got the Edel AFB hooked up. 10deg initial, 50deg total, 36deg max mechanical means the vaccum is adding about 14deg max. Pretty run of the mill. Completely by the seat of the pants, the ported vacuum seemed snappier off the line, with the manifold vacuum a bit more sluggish, which is...
Clearly here the Edel 1411 install manual says to use MVA for "non-emissions controlled engines", i.e. the 440HP in my 67 R/T. Interesting this is opposite to what was said in the above YouTube video.......but then again the pic has to tell you that the PCV port is "not for fuel".... so...
So I think have read or watched 20+ articles on the ported vs. manifold distribution advance topic. In conclusion for a 67 R/T 440 4sp with a very mild
hop-up to the engine (aluminum intake, 1-up cam, Edel Performer, stock heads 10:1, stock manifolds, etc.)
1 - earlier AFBs including the...
Was VERY faint, but magnifier I thinks showed 76750-2 and 3325. Prob means 750 double pumper, but for the life of me I can't find these numbers for a Holley carb on the internet.
So now that all you smart folks have got me on the right track, I will be getting rid of my Holley. The numbers on the air horn were VERY faint and seemed slightly double stamped, but under a magnifier was 76750-2 and 3325. Probably means it is a 750 double pumper, but I can't find this model...
So for the ones following my threads about the no snorkle air cleaner.......went to replace the Holley with a Edel 1411 AFB Performer. Found this:
- the really nice Mopar aftermarket intake PN 5153235 is 2" higher than stock
- that necessitated a recessed air cleaner base so as not to hit the...
So what I have found in a few places, is that the oil breather nipple on the side of the air cleaner identifies this as a 68 piece that had the mandatory California "Cleaner Air System" or CAS. Or a 67 that had the CAS that was an option.
--> is there any way to tell from the fender tag if...
Thans folks, especially Darter6. I have since learned from a bunch of internet research that:
Performer is an AFB with a larger 5 1/8" air horn. Main difference is that AFB secondariess are controlled by a counterweight, AVS2 controlled by a spring, which makes the AVS2 more adjustable...
So the original carb I still have for my 67 R/T is an AFB with a 4 7/8" air horn. Currently has a Holley double pumper that has to go, but want to get something new vs. rebuild the AFB which I probably would screw up. Can't get a straight answer from the tech guys at either Jegs or Summit. Is...
Thanks everyone. I think I will go with a 750 AVS2 with electric choke. The air cleaner will fit, and although the top has a breather nub like a 68, only the purist will know the difference. I really like the no snorkel look with the aluminum intake.
So this is related to the air cleaner couple of threads. The Holley has to go. I can get an AVS 750 with electric choke, which was recommended by one reader.
Jegs has them in stock for $459. There are multiple "competition AFB 625cfm" on eBay, they supposedly have a 5 7/8 air horn also. Also...
