GM Perf. Parts Serpentine setup

[k5kev]

Has anybody tried using this Big Block serpentine setup from GM Performance Parts in their 67-72 (GMPP #12498733)? I'm in the process of putting in a 502 crate motor in my 72 suburban (with dual A/C) and was thinking this may be easier than trying to scrounge up all the brackets, pulleys, etc. for a big block. Maybe even cheaper at the end of the day!

I'm kinda wondering if it'll be difficult to adapt the a/c compressor and the alternator. Probably have to use R134? I'm pretty sure I can get the power steering pump to work. Any advice would be appreciated. Thanks!

The only thing better would be if GM made that set-up for a short water pump

I put this set up on my zz4. It was very easy. The a/c lines will work, the power steering pump will need a cutom line made at local parts house cost me 35.00. other than that peice of cake. Looks clean and no more belt adjusting!

I have it on my 402 in my jeep...

I switched out my steering box to use a later model Chevy box.

Was easy, this is the incorrect belt routing...

Thanks guys, I think I going to go for it!

Watch the clearance for your radiator, the water pump pulley is super close with a long pump and the motor in the stock location. I kept my short water pump because of it.

thats the factory set up my engine came with. its a gen 5 454. it barely clears the rad. but its kick ass haha

here are some old pics

I put it on my 502 with the factory kit(pump,alt,pwrsteering pump,compressor). Biggest issue I am still working on is the clearance issue to the rad no room for a clutch fan and no room for electric fans. Right now I have a 12" and a 14" electric in front of the air conditioner coils and a 16" flex fan(no room for anything bigger) on a 2" extender. I am trying to make up a fan shroud to funnel the air better to the flex fan.
I just swapped the valve on the new pump with the old pump and all of the hoses to power steering worked.

It's exactly what i used on my ZZ454...

Well.. it's about half the price of the same getup from Vintage Air --

At $900 to $1700 for these setups .. I think I'll scrounge on my budget but I can certainly appreciate why someone with deeper pockets for their project might go this way.

Kfreddy, I Noticed You Used Newer Motor Mounts, What Type Of Exhaust Manifolds Or Headers Did You Use. Looks Like It Was A Tight Fit.

[k5kev]

I'm putting this on 4x4. It looks like you guys with tight fan/radiator clearance have 2wd. Doesn't the 4x4 engine crossmember sit farther back (2inches or so??) towards the firewall. So maybe no clearance issue on a 4x4??

Thanks guys.

Cant they dont make a reverse flow short pump, serpantine setups run the pump on the backside of the belt so it spins backward, plus why would you want a short anyway limited water flow, if you coming into this century with the serpantine why not use a pump from thios century, chevy stopped using them in the 70's for a reason

you can buy a conversion fitting from eaton for 4.50 at NAPA for this and keep your original line

Where did you find a reverse flow short pump and how did that work since they pulley wouldn't line up with the others

Not "reverse flow" but "reverse rotation". The flow is the same direction as any old Chevy. Just to clear thing up.

[rob32472]

if you by the kit from gm performance it comes with it

Same thing well sorta I can see it being misleading but what im saying is the direction of the pump is spinning opposite so it needs to have the impeller blades cut in the opposite direction. If you put it on the wrong motor it would be reverse flow and not flow well at all but it would still be backward sorry for the confusion

Still do they make a special pulley for short pumps? why would you want it due to limited flow capabilities? do they make a "reverse rotation" short style pump? again why why why?

If your not going with a concours build why run the short pump and serpantine would be out of the question anyway
