255deh or xe256
I've got a stock 77 F150 with the 400 in it. The motor is all stock, with a fresh bottom end. I've been thinking of getting a new cam to help the low end a bit. I want a stump pulling truck with tons of power down low but i don't want to change pistons or heads to do it, which I know will limit me some. After searching the site I've narrowed it down to these two cams - 255DEH or XE256. Keep in mind the motor is and will be stock minus headers and exhaust. I will be using the stock intake and carb, and I will of course dial the carb in after the cam swap.
So help me please - With a stock motor which cam will be best? Keep in mind, all I want is the best low end cause this truck doesn't see much open highway.
Thanks

The 255DEH is a little better at low end. It puts out 430 ft-lbs torque@2000 RPM vs 429 ft-lbs@2000 RPM for the XE256. The XE256 is much better at 3500 RPM.
These figures were simulated with a 600CFM carb and large tube headers with mufflers.

thats better? har de har. anyway...from what i've been told and read the xe is a bit more aggressive...my choice. with stock cr youd be happy with both...xe if more hwy in the 3k range but even that is negligible i think.

BTW, I hope that you are going to get the complete kit including valve springs. You are asking for trouble if you use the stock springs.
