I've decided to change cams in my 340. Looking at either a Lunati 60403 or 60404. My motor is a 30 over 340 with stock type pistons, J heads with 2.02 intakes, 780 Holley(3310), 3200 stall converter and 4.10 gears. I will install an air gap in place of the Weiand currently installed. We cruise in it a little and goes to the track 1-2 times a month. The cam currently in the motor is a Lunati 60043.
Which cam do you guys think I should use? I'm leaning toward the 60403.
