318 stalls in Drive

Hello, MOPAR Brain Trust,
My '84 318LA stalls when put in DRIVE. I"ve searched this forum and FBBO and found some useful information. But..... I'd like some more input on resolving my particular engine problem.

Here's what I got:
1984 318LA that's been 'cammed' up. It's in a 1975 D100 truck, 727 trans.
Currently idling at 850 rpm, put it in Drive and rpm drops to about 550 and most times the engine will stall if I don't pad the gas a little.
Stock flat top pistons and std. bore.
resurfaced heads, unknown amount
Timing 18 deg. BTDC static
Camshaft purpleshaft P/N: 4120231
I/E duration @.050 241
Advertised @ 284
I/E lift .484 (stock rocker arms)
LSA 108 (originally timed at "0", advanced cam 4 deg. Cloyes chain) This helped some.
Overlap 68
Stock 1975 Converter (i think thats a 1700 rpm stall)
Cast iron exhaust, duals.

Here's the kicker, I know you guys are going to 'facepalm'. It originally had a Weiand Action Plus 8007 intake. The throttle pressure (KD) linkage would not match properly. I installed the cast iron 2 bbl intake and Carter BBD 2 bbl carb with the stock KD linkage.
My reasoning being that the BBD is sufficient in size as the primaries as a small 4 bbl. Just wouldn't have much top end power, which is fine.


I bought the truck as a project. I want to sell it but, it has to have decent street manners. Not a lot of power.
P.S. I didn't build the engine. Never ran it with the 4 bbl intake.

I really don't want to replace the camshaft. But, bolting on a 4bbl and finding a stock iron manifold is a possibility. But, would that help my idling problem?
