So I plan on building my truck engine, but I don't know which cam would be the best, I haven't used any of these cams before so if you would help me out. I have an f150 5.0 that has a 4 speed tranny, 6 inch body lift, and its on 35s. I am pretty much limited to the letter cams for my truck and I am trying to find the one with the best low end power. The only other stuff I am doing is valve springs, intake, 4 barrel carb (650cfm), long tube headers with 2 1/2" true duals, and possibly a smog delete. I don't know which cam would be best for my setup though. Right now I'm thinking about the x303 because according to summit racing its operating range is 2,200-6,200rpms, which of all the letter cams i have seen so far it has the lowest range in the rpms. Some of the other cams start at 2,500, and one of them starts at 3k, which one will work best for me. My truck is used for some light pulling like logs or scrap metal so I need the cam with the most down low power.

I think you'd maybe be looking for low end torque; power spins the tires, torque pulls the load.

All the letter cams will suck for low end torque.

How about a stock HO Mustang cam with 1.7 rockers or maybe XE264HR from Comp.

I was reading about a ***** thumpr cam the other day in a 347 stroker and it made more low end power and more power in the high rpms then the other two cams they tested. would one of the ***** thumprs be decent for a truck?

I have the comp xterme energy cam (35-349-8) with gt40p heads. It works good. Great power down low great idle with some lope

I was thinking about gettin the 35-349-8 or 35-512-8.

How do you like the cam you have?

I have the 35-349-8 and I love it. It has great power at any rpm and it sounds great. In my opinion I think the letter cams suck for trucks.

What engine do you have and is it stock?

I have a 94 f150 with a 302. Its got gt40p heads from a explorer, comp 35-349-8 cam, and 1.6 ratio roller rockers, long tube headers, smog pump delete with the bypass pulley for stock size belt, and msd coil.
