Thanks for the reply's,I have the Holley 750 with 4 corner idle...i will dial that in, get what i can out of it,wires are new, but i will look into the distributor...I am fine with the idle/shake as long as i know its only a result of the cam,everything else being as it should...Anybody suggest baseline jetting w/older Holley 750 hp carb?

40/440(low comp)
performer RPM intake
1 3/4 headers
Hughes 30/38 cam
