Carburetor suggestions for 318

Timing and carb tuning are key. Especially the timing. There was an old mopar action article where you heated up the slots on each end of the dist where the weights ride, and hammer on a 3/8th bolt sideways to shorten up the travel. Then you ground it back flat. Its possible to get something like 20 degrees in the distributor with that method. I actually did a toyota 22r dist that way and it worked well. And I was amazed by how much power I was throwing away from the lazy timing curve.

Also, be sure that you do all these adjustments and checking and such with the vaccume advance disconected and plugged.
