Single or Dual Pattern Cam

318 will run, I'm wanting to get better performance from my 318. I've had a lot of good suggestions on the cam. I thought that since you have a 318 I'd ask you what cam you recommend. Compression ratio 9.40:1, speedmaster cylinder heads with 170cc intake runner's, 1.88" intake valve's and 1.600"exhaust valve's, comp valve job and back cut the valve's. Intake, edelbrock performer rpm, carb 650 edelbrock. Headers 1 5/8" long tubes. Ignition, stock mopar with a gm 4 pin module and matching coil. Gear ratio, 3.55. I haven't bought anything yet as I'm trying to put together a good combination.
