- 5.9 360 V8 Magnum
Rebuild 5.9 Magnum, bored .030 over, keg intake with the reduction plates welded in along with the plenum plate welded, UTP 450 Cam, stock injectors, new heads, shorty headers, true dual exhaust.
Custom Comp Cam from a guy named Marty Fletcher. Cam specs-
Advertised Duration 273 intake/273 exhaust single pattern high torque
Duration @0.050 215 intake/215 exhaust
Lobe Separation 108 LSA
Lift Intake and Exhaust 0.284" (0.455" with 1.6 roller ratio)
54 Degrees overlap
I am getting like 7 MPG and I can not figure out why. I used to get around 14 when it was bone stock with a leaking plenum and cracked heads. Now that I rebuilt it and made it all “right” (I hope) it gets terrible gas mileage. Is anyone else running this cam? If so what kind of fuel mileage are you getting? The truck is still pretty stock, I mean the only real big changes I made were the cam and the intake and bored it out .030 over. I can’t afford to drive this if I’m having to fill up ever 100 miles. Any help or suggestions will be greatly appreciated.
