yeah, i think my 235, in a '62 half-ton, has around 50 horsepower. uh, it was running great after setting the valves in july, or so, and then it slowly deteriorated in power to where i can't accelerate up hills. it's annoying. well, the timing is right, but i think there may be something wrong w/ the advance and/or vacuum, because, upon stepping on it, the distributor doesn't turn [physically advance....you know], and you can hear this distinct sucking sound, upon letting off the gas, from the floored position while cruising. anyways, i don't know what on earth to do, but it sure is getting on my nerves...any similar situations out there? advice, please...thanks a lot...-jeff
