    Transmission Issue ??

    not necessarily a bad switch or vacuum problem. Just the vacuum is running at +/- the cut out point of the switch. Their is a black and blue delay valve that may help.

    Transmission Issue ??

    the lock up converter is controlled through a vacuum switch. if you engine is producing the amount of vacuum it takes to just trip the switch it could cause it to cycle and engage and disengage the lockup . mine will on just the rite incline.

    Front coil spring rates.

    the big 10 came with a straight six stock and the heavy springs. a big block required the heavy springs upgrade for the standard chassis. yes 78 had big blocks in c10s. it will ride like a truck lol.. i definitely feel the road fortunately my seat are soft

    Front coil spring rates.

    spring rate 843# per inch of compression or 1060# per inch of compression. f44 big 10 is most likley the heavier 1060 of the two and will give you a stiffer ride. in theory the softer spring is longer so installed should give the same ride height.

    Tire Size

    tires and wheels can have the biggest impact on the look, ride, feel overall style of the truck. you need to match them to your liking. in my opinion old school 15'x look best on a square body. personaly im running 15x8 front and 15x10 rears. and i like them but thats my style.
