looks like you are loosing quite a bit under 4k, do you mind posting your cam specs?

 

3400 should get it done and keep it bearable as a DD.

 

this is the specs vs.s stock specs straight off the jim wolf site..

256deg .430"lift (compare to stock at 232deg. .346"lift) 219.5deg@.050"lift

I talked with my mechanic friend who installed these and he claims with as mild of a cam swap as these are i shouldnt lose any hp with proper tuning.. so i might go and try to get more street tuning done on my truck especially that 0-4200 rpm region cause that is where im suffering right now.. i might try to richen it up in that rpm area to 12.3 to see if that drops my 60' cause this truck likes it rich to produce torque in first gear.. after that 12.8 to 13.1 for max power..
