RE: '70 Shelby 428CJ carb questions ?
By Geoff - 07/23/2004 2:13:04 AM; IP 66.42.13.176
p.s.
I got curious & checked the Holley web site & they no longer offer even the auto-trans version of the 735 cfm 4150 vac. 4bbl. (they used to under their "O.E. Muscle Car" program.)

Like I said, I have a "sweet" 4279 list for the manual trans CJ, but, you don't want this carb, unless you're doing a 100% resto. I tried it, used the stock jets, then one size larger, then 2 on the primaries, played with the power valve and diaphragm spring....got bored....

I tried running it on my '69 428-SCJ pre-"Drag-Pack" drag pack car (& I'll sell it to you if you insist). It's a single accel. pump, vacuum sec. carb that runs a big split on the main jets, front to rear. If you have a stick, cam or headers (you don't have a shaker to worry about like I do), it starves you for gas with the tiny primary jets & small single accel. pump while waiting for the secondaries.....you can richen it up, but, it still want's to stumble off-idle.

I put the 4150-HP 750 CFM #0-80528-1 on my Edelbrock RPM and didn't even have to dick with the (4) mixture screws....it runs like a top, barks off idle, plugs are tan, 106 MPH thru the trap....and there's no choke horn to impinge on the air flow.
This thread, so far...
