Im sorry, ive been kind of winging it and skipping things here and there not only in my description but also on the truck physically. Ive been working on this for over a month in the little spare time I have had. The last couple of days ive been to sick to spend a full day at work but now I should be back in action tomorrow. Before I go back into this thing tomorrow I would like to point out that I had the heads off and when I put the other ones back on I did the rocker arm adjusting myself. If I over tightened the rocker arm nuts could that be causing my problem? Valves not opening all the way or something to that effect. Now back to ansewering some of your questions(the ones I can) the truck idles like a dream and seems to go very well in reverse(im assuming cause its a low gear and low speed) but dosnt do the greatest driving down the road. Seems to have very little power and top speed didnt seem like it would have been to much over 30 or 40 mph.
