AVS, 4027 vs 4028

[BLASTER]

Looking to get rid of the pinche 4CG on my 283/glide. I have always had a thing for the AVS over the AFB and am on the hunt for a 500CFM version. They float around ebay pretty good.

The 4028S is for a 66 Chevelle 327/275 with Powerglide and no A.I.R. Manual transmission takes the 4027S.
What actually changes between a 4027 and a 4028. Linkage appears to be the same.

Any Carter gurus in the house?

Nope? Any 1403/1404 Edelbrocks in the house?

my guess is the kick down stud may not be on the manual tranny carb but you can buy them i would get what ever one you want you can buy the studs for the kick down at any auto parts stores and happy hunting

Linkage appears to be the same.
Turns out the 4027 and 28 are 625cfm.
On the hunt for a 1403 Edelbrock or 9511 Carter right now. (500cfm AFBs)

Thanks for the input, though.

Get a "Real" Carter carb for it, trust me.

I worked for Carter for 25 years, fact is I sold a New-in-the-box #9511 500 CFM carb about 4 years ago on Ebay.

But, ......... get yourself an 'Original' '60's Carter carburetor, they are correctly calibrated, not a universal calibration that comes with all of the aftermarket units that were sold by Carter and now Edelbrock.
I'll stop now, because I don't want to write a book on the subject, but just pick up the phone and call John at the Carb Shop in Eldon Missouri.

Call John and he will set you up: http://www.thecarburetorshop.com/

Thanks Glenn! Actually been on the hunt for a real Carter in a 9400 series for my little 283.
