Well I posted on TC to see if there was a fault to my reasoning. Harold promptly answered. It all depended on if one of my measurements was taken BTDC or ATDC. One way would make it 212* and a 256, the other way would make it the proper 218*. Guess what, its 218*.. so the cam is after all right. But it is indeed 3* advanced as well. I really dont think 3* can add up to the missing 50hp.. So i've asked for a cam recommendation. Not sure if he'll tell me to go any bigger though since the truck does see some tow duty, and has 3.08 gears.

Put the 262 into desktop dyno and advance it 3+º and see what happens.

Maybe not think of it in terms of horsepower but in terms of the peak. Move the peak out, the higher rpm has more air/fuel to make that power.

NM about the desktop dyno thing, it didn't do it justice at all.
