ct?

Mike Yes the dual 4 ae going on a 350 built SB.

Tehi Thanks for the info. I'll check it all out. Dual 390's are going to be hard to find.

Great find, Denny, that crossram looks fantastic on a SB. I haven't seen one for years. A guy might need a little engineering help on the throttle linkage, though :LOL:

Thanks Denny Was working in my yard. They had already been sold.

heres some 390cfm 4 barrel http://www.northernautoparts.com/Pro...uctModelId=111

Or here is a better deal....http://www.jegs.com/cgi-bin/ncommerc...71&prmenbr=361

I added a third one...http://www.jegs.com/cgi-bin/ncommerc...71&prmenbr=361

Just a reminder, on the older front to back 2-4 intakes, they were designed for WCFB's or AFB's, so do some measuring if you use Holleys to make sure they'll fit due to their longer length over the Carters. Personally, I wouldn't have any hesitation (no pun intended) about using 500 AFB's. Adjust the linkage so that the primary throttle blades on the second carb tip in at 3/4 to 7/8 throttle. Unless you're turning some hellacious revs, the vacuum secondaries will just be along for the ride anyway. But that's just my opinion and it worked for me several times in my life. Your results may vary :LOL:

My brother gave me the same advice about the 500. Might do that.
