351w cam
I’m sure this is beating a dead horse, but I’m deployed in Afghanistan so I don’t have time to comb the fourm. I have a 94 f250 with a 351w and I want to squeeze a little more power from it. It’s going to stay mostly stock but was planning on a mild cam, headers and exhaust, intake, porting the intake manifold. Just want the expert help here to tell me what I can estimate for power gain and if that’s a decent enough build to make it get out of its own way.

Depending on what cam is in your truck now but knowing what I do of what cams Ford did install this cam will do fine.
A nice bump up in power without hurting the low end.
Torque should also see solid gains.
The biggest block to making power on the 5.8L FI engine is the intake. Below 3500 rpm it's OK but above that it will lose out to any of the aftermarket intakes.

You need to know what cam's in there now before ordering that cam. The stock F4TE that was used in the 351W roller is just a smidge less cam as is. You can improve it's lift by switching to 1.7 full roller pedestal rockers. It's specs are: 256/266 advertised duration, lift with 1.7 rockers is .445/.473, LSA is 116*. Yours could have this cam, or could be a flat tappet cam in that year. Pulling a pushrod and measuring it will tell you which cam is in it. The roller rods are a half inch shorter than the flat tappet rods. The roller rods are about 7.55" long.
