87 TBI pulleys - The 1947 - Present Chevrolet & GMC Truck Message Board Network

*78 Chevyrado* · 09-29-2011, 10:45 PM

I'm needing either someway to have a double V-belt pulley for my alternator or maybe swap over to the later pulley set like i had on my 87 r10, as it has the one wide serpintine belt on the alternator.

the alt. i have it pulling too much for the single Stock V-belt to take. either the belt slips, or i have to overtighten the pulleys. neither is good.

If I get a double groove v-belt pulley for the alt, the problem is finding the corresponding water pump and crank pulley to go with it.

If i get the set from a TBI engine, will my current A6 A/C compressor and 78 P/S pump still line up correctly using the newer pulleys?

If they're cheap, I may just go find a set and try this out.

Any thoughts?
