I have an 85' mustang GT 5.0 Ho engine in my 83'Ranger pick-up. I took out the roller cam and lifters.
I put a Howards' 487 cam, lifters and, push rods. I put an Edlebroke intake and Holley 650 crab.
I am about ready to crank it.
I need to know the firing order for it.
That will depend on the cam . 351 ,302 boss and HOs use 13726548 , standard 302 and 289 use 15426378, number one is always on the pass side front for both cams .
