o.k. i got the truck to idle, did a vacuum check on it in gear. the truck idle for about 15 seconds, long enough to get a reading. the vacuum gauge read 4 inches. so i ordered some 2.5 power valves.

the stock power valves in the carbs are 6.5 which means when i put the truck in gear, it opens richening the mixture and eventually killing the motor.

as soon as i get the valves and install them, i'll recheck the vacuum and keep you guys posted.
