Serpentine upgrade? Yes or no?

[mrbone]

Street 512 going in my 68 roadrunner to replace a mild 383. Considering 440 source alternator, pulley and bracket kit. But, wondering if I should upgrade to a serpentine belt? Currently running a single alternator V-belt- no power steering or air conditioning. Thanks for your input.

Serpentine set-up is quieter and prettier. It is only an upgrade if you can find pulleys akin to the factory set-up. I made the mistake of getting an underdrive set-up that saved horsepower but slowed down everything causing issues with overheating, the alternator discharging at idle, etc....That said, if you don't want to deal with those issues, make sure you get the correct pulley sizes. The Factory sized them properly so you don't have to.

With only WP and Alternator, I would not bother.

I agree with jcc however you may have issues with alt belt slipping with that 512. A serpentine system would fix that

I have only ONE thing driven by a belt ... the alternator. I use the 440Source serpentine crank pulley aand the ulley that comes with the alternator (Denso 90 amp). No tensioner. Works great.

I you're interested I also have the 440Source water pump pulley and alternator pulley for sale.

Its worth noting that they no longer show anything other than the w/p pulley on their website !!

JMO....but I think billet-serpentine stuff belongs on street rods. If your car is a resto-mod, it'll look at home.

I bought the package from SD Concepts many years ago for my 65. Have not used it yet though since the car is on back burner. I like it because of the easy to source accessories and service parts. Straight vane water pump, 94-02 Ram/Dakota/Durango/B van alternator, S10 tensioner, Sanden compressor, 99-05 Jeep p/s pump.
