As my project, '67 resto-mod LeMans, moves forward, I am looking at engine accessories; primarily the pulleys and front of the engine stuff. Water pump and front of engine is based on 1969 and up. The car is a factory non-AC car, and has power steering. I will be adding in an AC unit, most likely from Vintage Air. So, has anyone changed their set-up to a serpentine system? Is there a reason to stay with the typical V-belts?

Reason to stay V is cheapness. Serpentine's cost a pretty penny.

Cortcomp, yeah, it is a pretty penny for the whole set-up, but I'm gonna have to buy all the parts for either the V-belt or serpintine, as I am starting this from scratch for the new engine. If there is a definitive reason to go one way or the other I'd rather get it done now; if it is about the same as far as how it performs I'll let price have a higher deciding point. I really figure if it wasn't broken, why did all of the manufacturers switch over?

You can generally find a complete junker motor for cheap and grab all its brackets, clean them up, and use them. I find serpentine accessories quieter, but maybe that's just because they're a newer design? I find parts store alternators and power steering pumps for v belts noisier than serpentine ones, but then again v belt ones have been rebuilt 18 times.

Most people think i'm crazy, the noises i hear and am chasing. Most people couldn't tell the difference between the two listening.

I'd assume serpentine better at higher rpms?

Serpentine exists to save space. Period. End. Stop. It offers no advantage over V-belts.

My Pontiac engine had a March serpentine pulley system on it when I got it. It was constantly throwing the belt. The belt was 28 bucks. I went through 4 in 6 months. I tried everything to get the pulleys straight and lined up. Straight edge and all. It looked straight. Even took it to a good friend to see what he could do with it. Could not figure out why it was throwing the belt. I was done with this junk. A 1300 $ March pulley system. I never would have spent that kind of money on that kind of system. I located some factory pulleys on eBay and brackets. Put it all back on. The factory system with v-belts are flawless. Not one issue at all.
