IMHO the q-jet throttle plate on that carb is GOLD and the correct linkage for the intake & correct q-jet makes an even bigger nugget of gold. only thing missing is the q-jet duel snorkel air cleaner that came on trucks.

take the lower plate from that smog q-jet and replace it on a early chebby q-jet with the #704xxxxx and it is awesome on SB mopars.

I have a mercruzer q-jet that I did that with and it only has a vac port for choke pull off and one ported vac for dist canister. no PCV vac port and it is jetted a little richer than a car/truck q-jet stock calibration. the 318 loves it.
