I put hei on the truck last night and a tach. I already changed the gear to a 3.42. Without being scared of over revving, i laid into it pretty good, and was pleasantly surprised. It has a bad cutout when you first get on it, but I think it is b/c of the junky reman Monojet the p/o put on. It leaks gas anyway every time you shut the motor off. I think that rod is worn out. There is some valve chatter at around 4000 rpm, probably a timing issue. I am going to check those dyno results out asap. i am thinking that if I keep the six, I will keep it kinda mild, since I have another one I can go all out on. I am really enjoying this process, and will post some before pics of my engine when I can. Thanks guys for all your help!
