Building a 5.9 Magnum fresh short 9:1 comp Eddy Magnum heads minor cleanup Eddy airgap intake(dual plane) 750 Demon carb 1 5/8 longtime. 518 trans 2500 conv with lockup. 3:55 gears. Car has power brakes is a pro touring type build with big brakes and all the handling tricks you can do. Car goes to the dragstrip 2-3 times a year is 98% street driven. Looking at a few off the shelf cams Comp xe274hr or the Lunati 20200715 or 20200711. I have 1.7 Harland Sharp Stock 1.6 rockers &1.5 Scorpions. Opinions on real world experience please. Max lift would be 565 based on piston to valve clearance. Leaning towards the Lunati 20200715 with the 1.7 rockers puts it at 550 lift and 213/219 @50.
Thanks mike

I’m running in the wife’s car a roller cam 360 block with the Hyd roller version of the comp cam. Slugs are the Federal Mougal c116hp (think KB-107) @ 0 deck, TF heads (11-1) & 1.6 rockers, dual plane, 750 & TTI stem to stern.
Trans is the original 904 with a custom Pro Torque 2400 stall & 3.55 gears on 26 inch tires. Yes the converter is a bit tight but it flat out works great.

The car is 93 octane, super driveable, gets reasonable mileage, good torque off the line and nice top end hp.

I myself would step up in cam duration. But it is not necessary. I myself would use the 1.7 rockers for more lift to take advantage of the heads good flowing ports. But it isn’t necessary. Both of these things are only really seen or felt in the top end.
