67 and 68 manifolds where the same casting number. There was a discussion on this in another post awhile back. Some AFBs had dual bolt patterns

Just to toss out a complete guess, if it's an AVS I'd bet short odds that it's a 4966s which was a very commonly used as a "one size fits all" replacement. No no no. That's a 71 440HP carb GG says so

All 67s 440s used large bolt pattern, 350 used a Holley, 375 used large bolt pattern AFB. Correct! All 440 engine 67-69 model years used the 2806178 intake manifold. Wide bolt pattern. We are talking M code 440 Cudas to grandmas town and county station wagon, to Mr. Drysdales Imperial convertible. Same intake manifold guys. 1966 and older RB intakes were narrow pattern, all 1967 and older 383's were narrow pattern. So Morty the 1967 440 is the only AFB car that can take an AVS on the same intake. Yes it can have an AVS but Chrysler didn't put it there. The 67 300 440 LP 350 horse engine came with a Holley and not very reliable. No surprise it was replaced with an AVS which is more common and with the air door adjustment its very easy to get them to run good. I've never seen a 1967 car with an AVS from th factory. Look at the parts book and shop manual, no AVS in there either. The air cleaner base would have the large hole for AVS instead of small hole for AFB. But you can get the base or the entire air cleaner form the car that donated the AVS. Choke thermostat is different also. Fuel line the same.

No no no.
That's a 71 440HP carb
GG says so
.....Yes,yes,yes, , and it was commonly used as a one size fits all replacement, most I see are dated post 71 production, dated 1972,3,4, etc.

Didn't he though! The AC compressor was covering the pad I wanted to get a letter off of, but the eng sure does look OE/untouched.

Dog after seeing him today I dont think it will change hands but I will keep the AP difference in mind cuz I did get jammed up over that once on a prior build (had to end up buying 2 kits).

Chevy used an AVS in 1966 on their 327 275 HP engines, number 4028SA Had my hands on one of those many years ago. A friend of mine had a '57 Chevy (283 two barrel). I found him the '66 intake and carb for $10. I rebuilt the carb for him. By the time he was done he had a four barrel on his car for about $30. He still couldn't beat my '66 Barracuda...
