it seems to have power in the low end but at 65 when i pull hills in our part of the country it seems to pull down as much as 5-10 hr the hills in my estimation are not that steep. i really apprectiate your continued feed back. Do have any feed back on my tranny problem?

Of all the E6 & E7 heads all had the S or T cast in the corner. And if I ain't mistaken, the GT40P heads have a "P" there as well. They also have vertical bars on the ends of the heads, but that's sometimes hidden by the accessory brackets.

Guys, I can't tell you how helpful you are being to a new enthusiast, I looked at the heads and they are stamped with an "R". What does that tell me. Next there was a comment made about world steel heads and 210cc versus 180cc can you make english out of that for me. I know that the smaller 58cc combustion chambers equate more compression thus more horsepower.

According to what Conanski posted , you've got E5AE heads. Chambers are big at 67-70 cc's. Swapping to a set of 64 cc heads will raise the comp ratio a half point, to 9.0 to 1, if you've got an 8.5 to 1 ratio. Swapping to a set of 58 cc heads will give it another half point boost, to a total increase of one full point. As for those World heads, the 210 and 180 numbers are the intake port volumes. Smaller volume gives you better bottom end, larger gives you more up top. On a street driven truck, you'd want the smaller heads. And how it acts after a head swap also depends on cam and intake choice.

Hemieater, I went out and checked my linkage from carb to tranny, i took the linkaage off the tranny and the tranny lever sets at the very top and when i attach the linkage there is no movement. when pressing th gas pedal down the linkage responds instantly with a downward push. By the way what is the 3/8 square shaped bolt just by the lever for.

I don't know who gave me the advice on the tranny but my problem tostart was that i couldn't get the small screwdriver tip straight into the hole of the modulator valve, so i bent a small pocket screwdriver and turned the valve nut about 3 1/2 turns and the jerking problem seems to have disappeared.
