Serpertine Belt for 1971 Avanti

[GAWen]

Gentlemen, I know that some of you have converted to the one piece belt system, and I once saw a web site that had the complete kit, for something like $790.00. Well, I am saving my pennies, planning on doing a engine rebuild and a drive belt conversion, along with a 4 wheel disc brake installation. Major dollars need to be set aside, but I need to know where to get the pieces/parts I want.

I have the GM Performance serpentine system in my '70. You can buy the system from Summit Racing, Jegs or most any speed shop. The price you mention is about right for the system. Summit sells it for about $766.

You will have to modify your fan shroud for it, plus grind off a bit of the idler assembly so it doesn't contact the hood. Also, you'll have to get all new a/c hoses made up as the original hose ends won't be compatible with the new compressor.

If your '71 is like my '70, the alternator was originally on the right side of the engine...the serpentine system puts it on the left, so some wiring harness changes have to be made. If your car has an external voltage regulator like my '70 did, it will be eliminated since the new system comes with an alternator with an internal regulator.

You'll also need to buy a new reverse rotation fan and fan clutch since the new water pump will be reverse rotation.

It's a nice system, but don't expect it to be a simple drop-in installation since some mods will have to made for an Avanti.

BTW - a new crate engine is likely much cheaper and easier than an engine rebuild. For the same money you can get a new, better performing engine than the original.

You can remove the shroud and fan and install an electric fan kit like I did.
