Serpentine vs V-Belt?

It gets really hot in La and I am considering putting the Gen IV Vintage Air in my 67 (that did not have the air option factory installed).

One option is to convert pulleys to serpentine blets.

Any suggestions about whether this is a good idea? It is not the original engine block anyway so I am not able to stay looking original. Thanks! Pete

Are you talking a full front runner system or just changing the pulleys?

I had a March Front Runner system and Vintage Air on my last 69. Liked it but expensive.

Did VA and V Belt System on my 55 Liked it and it worked fine.

I have March Serp Pulleys on my new 69 and I'm doing VA with the serp belts.

If you only need a couple pulleys then the V-Belt will be OK. If you're changing all of them then I'd go Serp Pulley.

If you need a new water pump, PS pump Alt and everything then I'd go Frontrunner for the money.

#1 choice is any case is FR if you don't mind spending the $$

Re: Serpentine vs V-Belt?

Thanks for the feedback. I only have one belt now for the alt. Was thinking about putting power steering also. With the A/C that would make 3 belts. I can get the pulleys with 3 grooves to handle the job or go with your suggestion with FR. If I plan to use have PS and Air, do you think it's worth changing my existing Alt pulley and ordering the PS and Air with the serpentine option? The FR pictures online really look nice.

All depends on your budget. You would also have to change the WP Pulley and the Crank Pulley. I have March Serp Pulleys now and I really like them. Especially when looking a $1600 or $1700 to go FR

Alt, PS, AC, WP

V-Belt - 2 Belts
Serp Pulleys 2-Belts
FR - 1 belt

Re: Serpentine vs V-Belt?

Worth checking out GMPP options. Back when I was looking at options a few years ago they were offering a complete system that included a/c compressor, tensioner, all pulleys (can't recall if PS pump was there or not but wann sa it was) for like $650. It was a great value but I went for bling and got the March setup but will regret that decision some day when I'm ready to put A/C in. the car.

Re: Serpentine vs V-Belt?

It really all about how much money you want to spend and what kinda look you want.

They both work good.

I thought the serpentine was the way to go and not have belt squealing but they both will squeal and slip.

Re: Serpentine vs V-Belt?

Note on duel Vs always buy/replace as a matched pair..check the manufactures batch number on the belts are the same.
The slightleset difference the belts tension diferent and one ends up slipping...not being awere of this (as I was once ) one chasses sqqeeling belts around and often ends up in expensive upgrades (or blamed on a non existant blower lol)

Re: Serpentine vs V-Belt?

When a serpentine belt fails, it takes out everything. When one accessory fails, it takes out everything. With multiple belts, at least you have a chance of still being able to drive. The only failure that will stop you in your tracks would be the belt that drives the water pump. I think all that front runner stuff is ugly, expensive, and too modern looking. To each his own, though.

Serps fail way less often then V.

Each to their own but this ugly?



This Is my new 69 with the March Serp Pulleys. I'll add AC this winter.

Re: Serpentine vs V-Belt?

Been lurking a bit, but seen this, and had to reply.

I agree with Chuck myself. The serpentine stuff looks ugly to me, but I like period correctness, and wont own a new vehicle.

As far as serpentine lasting longer, I cant even count how many serpentine belts I have replaced on customer vehicles this year so far. Most of the time the idler is the failure, either by sagging at the pivot, or bearing failing, then it takes out the belt. They may be built better for aftermarket conversions, I'm unsure about that, but the factory stuff is weak.

Im my book if any belt fails u deserve to be stuck in the middle of a desert for a week at least.
Been driving over 40 yrs, normal cars, but by far mostly vintage and classic cars, 100s and 100s of 1000s of miles hate to add up an extimate.....I have flicked a belt off 2x times and taken it easy to the supply store once....
Belt maintance is no different to oil, ball joints, cooling system, air cleaner.
If u dont have the confidence to just jump in the car and drive 5000 miles without a thought...it should not be driven to the local store to buy a bottle milk.

Almost every new vehicle today is serp. Why because it's more reliable period.

And I'm guessing you've changed more serps lately because very few have V.

How many miles on those belts you changed?

Personally I've never had a serp fail. This includes my 2004 Supercharged Vette (serp driven), My new C6ZO6 and my other late model trucks and cars.

My very 1st post I basically said they all work great. If you want OEM period look great. If you want a different look great.

My preference ,budget allowing, is Front Runner, 2nd Serp Pulley and 3rd V.

Modern serpentine drives are w-a-y more reliable than v-belt systems.
Even industrial applications of multi-belt drives common for motors have gone the way of the Dodo.
In a 1600+HP synchronos drive we installed several years ago for a petroleum scrubber the belt was a single banded rib-drive with a hydraulic tensioner (or a "serpentine" ) vs. the multi-belt drive it replaced.
The reasoning is simple - more reliable - more drive contact area - longer life than individual belts - no probel with belt 'miss-match' causing early single belt failure - cost is less vs. multi belts. Besides, the failure of one belt requires removal of most of the others anyway in service, so this system is less time consuming to service as you just loosen the tensioner and replace the belt. (note: this sytem is triple-redundant anyway, so one unit can be rotated out for service down-time for short periods but needs to be returned to duty/stand-by ASAP.)

As far as set-ups ...
I would recommend you look into the Classic Auto Air system for your AC and their new "Resto-Mod" drive system. http://www.classicautoair.com/Restomod_drive_kits.html
I've installed one of these systems in a 'vette (w.BBC) and all I can say is it was the easiest and best fitting system I've used in quite some time!
The owner ordered the black-anodized system and with his black and aluminum engine it looked very trick and clean.
I really like the parts selection, fit and function of the Classic system vs. the Vintage system (even though I should be more attracted to the "Vintage" name ) and the system being designed to use your original controls is a big plus.
They can even do an "OEM" type system if you want.


Oh, and no - I don't work for Classic Air ...

Re: Serpentine vs V-Belt?

I always thought a serpentine system was a single belt system. A lot of what folks are calling a "serpentine" system is really just a glorified 2 or 3 belt system with wider - and likely more durable - belts. For SBC anyway, a true serpentine system generally requires a reverse rotation water pump.

For the money some people spend on these systems, the old factory v-belt system sounds plenty good to me. The old v-belts are inexpensive and readily available and do a great job for their intended purpose, and most of the brackets are on j-hooks at the parts house.
