PULLEY PLATING
 

IM AM SURE THIS HAS BEEN TALKED ABOUT BRFOUR BUT WHERE ALL THE PULLEYS ON A S/B BLACK OR NATURAL CAST GRAY FAN / CRANK / PS / SMOG /

Re: PULLEY PLATING
 

In '69 for the Camaros the pulleys were phosphate plated (crystalline black finish) and later in the year and into '70 they were painted black.

I thought they were dip painted

CAR IS A FIRST WEEK OF JUNE BUILD I HAVE SEEN THE PULLEYS BOTH WAYS AND NOT SURE ON WHAT IS CORRECT

Re: PULLEY PLATING
 

The earlier '69 production had the plated pulleys, by June '69 I would think the painted pulleys would be most correct.

Re: PULLEY PLATING
 

The plated grey pulleys look way better then painted.Is there any original cars after june with plated pulleys?I usually plate the smog grey even for the later then june cars.Is this the wrong thing to do?

Re: PULLEY PLATING
 

Looking at the '69 Camaro smog pulleys most of the original 458 smog pulleys I've seen are painted black. I don't think I've seen the nearly black manganese phosphate plated pulleys used much after early 1969. My Jan. '69 built Z had the nearly black plated 458 pulley. Original mid-year '69 smog systems I have use the painted pulley.

Remember this thread? SHP BB set up from a July built COPO. Pulley is painted. I recall plated pulleys had a hard-stamp part number, ink stamp on painted pulleys.

I think the later '70s NOS painted 458 pulleys were the ink stamped version? The '69 painted 458 pulley was hard part # stamped as were the same pulleys into '70 certainly.

Re: PULLEY PLATING
 

The GMPD service #3932458 pulley circa 1980s was painted black with an ink-stamped part number. Bought some in the CPX days; think list price was about $5.

The crank and water pump pulleys on my 1967 Norwood 11B convertible with 327/275 are grey plated. This seems consistent with the original cars I've seen. I have a few sets of these pulleys from this era and they are all plated except for the LOS AC pulleys I have which are black. Not sure if they are plated or painted. The AC pulleys came from a very original parts car in San Diego so I don't think they have been painted over the years. Anyone know if the installed pulley finish was mixed or plant specific?

Re: PULLEY PLATING
 

There are 4 pulleys possible (crank, smog, ps, wp) on a car. 27 pulleys used in production in 69 Camaros.
I don't think it's possible to make blanket statements about them. They came from different suppliers with different processes.

Very well said Kurt [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img] I find it amusing at times that some guys want all aspects on the build of these car's and there components spelled out in black and white almost 50 years later. Pulley finish is just one of many we could talk about, JMO.

There are certainly many variables with model year, plant, time of year etc. My experience has been primarily '69 Camaro, both plants. We are all trying to do what is most typical of when our cars were built; part finishes, under-body oversparay, trunk splatter, dash finishes, body color match, etc. The survivor cars are the best examples, even if there are very few true survivors. The excellent survivor 21k mile '69Z in hugger orange at the MCACN show was great to see. Even that car had an original non-deep groove smog pulley from the factory, certainly not typical.
