What is difference between these March Serpentine pulley kits

[cris67chevelle]

Hey was up everyone I hope you guys had a great and relaxing weekend. I am doing some research and I need some of your feed back. I don't have my engine built yet but the engine I plan on putting in my car will be a 383 stroker motor probably 450hp to 500hp. I would like to put a nice march serpentine pulley kit on it but I want to know the major major differences between these two kits. One kit is called a "Style Track" and the other is called "Ultra Drive" if I am not mistaken. I have the links below: Any input will be helpful thank you.

Setup #1 looks like some bull**** done up for a clean, aesthetic setup. Looks overcomplicated and difficult to work with (swapping belts, alternators, making adjustments, etc).

Setup #2 looks much simpler, I would use this option. It is adjustable using a tool at the top of the bracketry...based on the instructions it appears easier to adjust, simpler, easier to install, and has fewer parts. Also costs less.

Cool how about the alternator amp wattage, the more expensive one I believe is 140 amps and the cheaper one is 105 amps, will this play a big role in the engine I am going to be using?

I would honestly not purchase all of the engine components with the kit (water pump, PS pump, alternator). You can get better components by individually selecting them...I would literally only use March for their pulley kit...you can buy a pulley kit without all of the extra parts.

You can get a much better alternator (aka CS144) for a relatively good price. It is modern, digital OEM technology and really does outdo the outdated SI series alternators. Call National Quickstart through their website: www.alternatorparts.com and they will hook you up with a brand new GM CS144 (140 or 170 Amp) with the conversion harness, fan, and your choice of serpentine or v-belt pulley installed and ready to mount. All you need is a quality metric bolt from the hardware store to thread into the alternator.

For the water pump try a Stewart/EMP Stage 2 available through Jegs or Summit Racing (note you must use a Stewart Thermostat as well).

Honestly this sounds like a whole lot of extra hassle for nothing...but these are better parts and will function superbly. You will be happy in the end that you went with the best parts available (and they aren't even much more on the budget).

As for the pulleys themselves March does a very good job and puts together a high quality kit with straightforward instructions. Try this kit, I'm using it on my current build; it uses serpentine belts but the old-school bracketry with extremely easy-to-use turn buckle adjusters which can be messed with on the fly:

P.S. If you do go that route make sure you buy the kit suited for your Power Steering Pump (keyway or press-fit pulley).

i ran the style track last year b/4 my ls swap. it worked great, but i would recomend getting the tensioner thats optional. its not cheap but it works alot better than the b/s tool that comes w/the kit. i had to continually adjust mine.

The ultra Drive is a great system and was developed a few years ago. The Style Track is a new system that does everything the Ultra Drive does for way less money.

We sell a lot of Style Tracks and they are a good system and come all quality components including Sanden Compressor, PowerMaster alternator and Tuff Stuff power steering

I also recommend the 21155 with built in PS reservoir instead of the 21150 which requires a expensive remote reservoir and hose kit.

What ever you decide we can make you a good deal on March products.

here is a pic of a system we just finished on a Smll Black 383 69 Camaro

BTW, we have a $60 upgrade to the 140AMP alternator not available elsewhere.

Dammit, more money to spend with ya... :)

[cris67chevelle]

upgrade = $$$$$$$$$

lol always thats fine you get what you pay for. :bsjerk:

Most cars do not need a 140 amp alternator. So to keep cost down a 105 AMP serves most. but in our world of Pro Touring we sell to a lot of guys with A/C, Stereos, Hell dual fanns pull 35 amps them selves. So we recognize the need for the bigger alternator. So we can substitute it.

And the 21155 is $100 more then the 21150 but save you $330 on the hoses and reservoir.
