After accepting the fact that my truck is cursed after cooking the bearings in the original motor and a junkyard block that I rebuilt myself, I decided to look into the ATK Engines 360 Magnum that is purchasable on the Jegs website. It wasn’t until just now that I realized the camshaft is ever so slightly bigger the exact specs are listed below. But with my ECM being 1995 (the final year of using OBD1) my tuning ability is near impossible and I just wanted to know if the camshaft being ever so slightly bigger would even be a problem or if the O2 sensor or PCM itself will compensate for it.

• Camshaft: Hydraulic roller
• Advertised Cam Duration: 251 Intake; 271 Exhaust
• Cam Duration @ .050 in.: 188 Intake; 194 Exhaust
• Cam Lift: .411 in. Intake; .418 in Exhaust
• Intake Centerline: 116 Degrees

 

Stock computer may be friendly with it, if the cam doesn't stray too far from stock. Or maybe a mopar performance PCM??? Though those are REALLY hard to find these days.
