ya they called and said the truck idles fine but acts like its out of gas when you drive it....and did esxactly what they said i talked to mti in houston texas speed and 3 other shops and they all said my cam would be fine with my setup...so theres no reason for it to be like it is unless the guy just didnt know what the hell he was doing right? like i said i ended up colapsing 3 lifters and ordered new comp cam 875 yesterday....any bodyhave any thing at all?

Check your fuel pressure?
Also, I would definitely run a converter with that cam in that truck...
