What suggestion would you give for a 383 stroker, 5.7 rods balanced, Holly 600 cfm 4150, 700r4 trans with a 2400 stall in a 71 GMC short bed. I'm looking for a real rough idle, not worried about vaccum.

This is what I'm thinking.

Your best bet will be to determine your exact static compression ratio and call the cam grinder for a recommendation.

You're gonna need more carburetor.
