[87BOSS351C]

a cheap way to change to a standard rotation w/p and get a grooved w/p pulley is to get the pulleys (crank and w/p) and even the water pump from a mid '80s Lincoln 5.0. I did this to convert my 351C to serpentine belts for $10. My pulleys cam from an '86 Town Car. One note is that there are 2 belts driven off the crank, so you can't use an underdrive crank pulley anymore. just use the front groove to run the w/p and alt and ignore the rear groove. You do, however, endup overdriving the w/p and alt a little bit, good for most street driving, bad at high RPMs at the strip. You may have to shim out the alt a little bit too, so things line up.
