NO 383HP (335hp) c-bodies!!




I was told that the 69' road runner auto a/c 330hp used the Carter 4638.
Is this wrong?



Yes the AVS-4638S was used on the 330 hp engines.

The 1969 Shop Manual lists the following carburetors and the engine/transmision:

I added the horsepower ratings obtained from several different sourcec.

AVS-4615S 383/manual/330
AVS-4616S 383/automatic/330
AVS-4638S 383/automatic/330
AVS-4711S 383/manual/335
AVS-4682S 383/automatic/335
AVS-4617S 440/manual/375
AVS-4616S 440/automatic/375
AVS-4640S 440/automatic/375
Holly R4166A 440/automatic/350

It lists no 383/Holly combination.
