BBK Underdrive pulleys
Now i know that this topic should be searched for and i did, i promise, I just couldnt find the exact answer i was looking for. What bbk pulley set will work on a 305 tbi
PN 129-1620 1988-92 TPI
or
PN 129-1603 1988-95 GM Truck 4.3, 5.0, 5.7L w/alternator with ext. fan
that is the only listings that i think would work. The reason i think the 88-92 TPI pulleys will work is because march sells a set that work on 88-92 305 or 350s. Which one will i need, how do they perform etc.
also will i notice a difference at idle (for instance, when i bypass my smog pump) with the amps to the alternator and cooling.
thanks
