OK I have a 1997 F150 4x4 4.6L. Just got a set of 2001 heads, upper/lower intake, yadda yadda yadda. I am going to P&P the heads and intake and all. I want cams to help with pulling. Power down low. Will never be raced so do not care about top end. I have searched and 99% are for guys that want top end.

 

call some cam companies, cpm, crane, etc and see what they suggest

 

Usually a cam upgrade requires a programmer and you didn't say if you were going that route. Here is the catalog page for the 4.6 and 5.4 Ford engines from Comp Cams. I have the 102100 in a 4.6 for pulling horse and hay trailers and it put a lot of grunt in the little engine. I do not have any programmer or chip, just the factory specs. I also have the 3.73 T-Lok gears but the 4.10 would be a better choice.

I have the Comp 102100's ( aka 262's) as well. Mine are on a blower engine and they work well. They are fairly mild with a very slight lope. 410 gears are a good idea too.

 

Built 54 suggested the comp cams 102500 on my N/A 97 4.6L the RPM range for the cams is like 2,150-5,400 RPM So they have some down low. and all threw out the RPM range.

 

Sorry forgot to add that yes this truck will be dyno tuned.
