I thought i would share a update after 500 miles.

I couldn't be happier with the setup. Next tank i will check the millage and report back. The truck runs through the gears fast and gets up to speed so easy i forgot what the old tired motor felt like. The gears and OD possibly make a bigger improvement than the motor.

I do get a soft code ( i think it is the EGR) once in a while if i am driving real light throttle at cruise speed. It resets when the key is turned off and does not reappear for days. Next time it happens i will try to grab the reading before it resets. If it is the EGR, i got the same code before the new motor so i do not think it is cam related.

As for the cam (flat vs roller). I do not think i will be upgrading the heads or to a roller. The motor has nice instant throttle and for 90% of my driving it has more than enough power. I also do not think the worries about the oil is justified on a stock valve train at .450 lift. If it were a .650 lift with huge spring pressure i could see the need maybe.

I hope this thread helped someone.
