Looking for a cherry TPI (not TBI) serpentine crank pulley- no dings. davefarr1967@gmail.com

 

I believe the ac delco of canada or gm p/n you are looking for is 10055879 tbi and tpi on the cars is the same. Tbi truck uses a different offset.

It's the TBI that has me confused- this is a truck application and I know the TBI is 1/2in shorter. Didn't know the car TBI was different.

 

with the tbi to tpi conversion in a tbi truck you need to replace the crank pulley with a 88-92 tbi/tpi the water pump will work because of its width.The power steering pulley is the same. You also need to run the accessory brackets from the 88-92 f-body to get the upper radiator hose to clear the serpentine belt.

 

Been running this for set up years- but lately having serpentine issues with stretch and wearing out too fast. Was looking at the crank pulley and can see some stone dings and roughness- must have hit something. If the car TBI/TPI pulley is the same-I just ordered above part # and hope it's the right one. My dealer wanted $108cdn and PartsTaxi wants $79....Mine measures 3.25in out from the harmonic.

 

If you look at the amazon application listing looks to be the right number. this same pulley was used in the gm performance parts serpentine kit for sbc. the amazon is the cheapest I could find and free shipping.

 

I ordered it- not worth playing with used. It does say Camaro and Firebird, the only thing that bothered me was it didn't specify TPI. Thanks for your help.

 

Was this the correct one ?

 

Haven't recieved it yet- figures that today found the same at the local dump- with full serpentine brakets on an old caprice, will install soon.

 

Figures you never see those around or at least were I live.

 

Yes, me too- I think 45min well spent. Had the 120a alt too with the adapter plate.

 

you got hooked up, Ill gladly take them off your hands Ill send you my shipping address.

 

What are you interested in?

 

I am interested in a few serp parts but as of now finds are low
