Alternator Brackets

Hi, Why are the 302 and L79 alternator brackets different from a regular 327. And any pictures of the lower bracket for both would be great, with stock manifolds and headers.

Thanks, Ryan

Re: Alternator Brackets

I believe it is because the Z/28 uses a deep groove pulley system to prevent throwing belts. Pulleys have a larger outside diameter than the stock pulleys with the belt kept well down in the groove.

Re: Alternator Brackets

Thanks Big Dave. Also forgot to mention I was referring to 1967 if that makes a difference. I have a L79 for my '67 w/ P/S and need some of the pulleys and brackets. I hadn't thought of the deep grove pulleys.

Re: Alternator Brackets

You can find a list of the factory original pulley numbers here (they are no longer sold by Chevy but they were all stamped with a part number if you find a used one on flea-Bay.

Camaro - Engine

There are also reproductions sold by many of this boards Sponsors (it is good to give them money as they give some of that money back to us to pay the bills to keep this board running).

Re: Alternator Brackets

Thanks again Dave,
I was looking at that list the other day. That's what sparked my question on why the different brackets.

Re: Alternator Brackets

So I am thinking I should search the catalogs/venders for brackets and pulleys for a 302 since Camaro didn't come with a L79? Example: some bracket applications say for 302/350 same and 327 is a different number.

Re: Alternator Brackets

If you want it to be stone stock. I covert my projects over to a five or seven rib serpentine belt system since you can not throw one no mater how high you spin it, nor do they slip the way a V-belt does. You can also get billet aluminum pulleys and brackets for about the same price as reproduced stamped steel ones. I use March or Zoop as a vendor.

Re: Alternator Brackets

I have been researching all this pulley and bracket stuff and I think I can use the 302 brackets with the non deep groove pulleys? My Harmonic balancer is 6 3/4" and matches my timing tab.
