Re: L88 pulleys C3

Most likley, the car would have been equipped with water pump pullies GM #3848904, a 2 groove inner pulley, "sandwiched" together with a GM #3883235 single groove outer pulley (for AIR pump drive). It's also possible that it could have been equipped with a single 3 groove pulley of GM #3889372. I would consider the 2 pulley configuration much more likely, though, especially for an early 1969 L-88.
The crankshaft pulley was GM #3863108, a 2 groove cast iron pulley.In Appreciation of John Hinckley -

Re: L88 pulleys C3
I would tend to agree with Joe, would normally expect to see the two groove W.P. pulley with the single grove added for ath A.I.R. pump.Dick WhittingtonComment

Joe and others, thanks for the assistance. Is it possible to direct me to a picture of the 2 groove pulley Joe referred to? If not, how about the dimensions of the diameter and heighth? Thanks again Dale.Comment

Re: L88 pulleys C3
Dale, the best I can do is a 5 1/2" O.D. Without one to go by, all else that I can tell you is that it is rather deep, the hub mounting flange is slightly in front of the pullies. Not as deep as a lot of the small blocks, but slightly (maybe 1/8-1/4) inch past the pulley.
If you are who I think that you are, why not go to your friendly Meineke muffler shop and look at one of his cars.Dick WhittingtonComment
