Just kind of curious if anyone has run one a PS pump that wasn't from a truck. It's not a quantum leap or anything special, I realize that, just curious if anyone has done it, and if it was even noticeable. I ended up having to use the belt system off of a 1986 Monte Carlo SS, which has the serpentine Alternator/Water Pump/Crank belt, and a seperate PS pump belt to the crank. Since I didn't want to change pulleys (and my old truck PS pump leaked, made noise, and had the cold jitters) I used the PS pump off of the car. The car pulley is relatively huge. About 7.5" in diameter, so it should reduce the amount of PS assist I have. I bet the stock one I pulled off was maybne 6" diameter. (Have heard it was to make the 305 appear more impressive, although less steering assist gives better road feel too) Personally I thought the stock truck one had TOO much assist, even with the 33" tires, so this will probably be fine, just wondering about others experiences.
