Big Block Serpentine? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

CG · 07-07-2020, 07:32 AM

Is there a budget way to put serpentine belt system with a big block that has air and power steering?

I dont want to spend the money on one of the fancy aftermarket systems.

How about a serpentine system off a mid 90s Chevy truck? Lots of folks, including me, have done this for small blocks, it’s cheap and easy. Should work for your big block also. If you find a big block truck in the wrecking yard and decide to go that route get everything, all the little brackets, fasteners..... the serpentine systems are reverse flow from stock so you will need the correct water pump and clutch fan.

x2.

I used the KWIK Perf adapters to allow using the 88-95 SBC/4.3 serpentine set-up on a BBC. The only thing additional I needed was a water pump pulley spacer for improved (for me) alignment.

Didn't the last TBI 454 trucks/Suburbans have a serpentine setup?

Yes, the BBC TBI trucks had their own serpentine set-up. But, it's not as common nor compact as the SBC set-up.

That was the driving influence for me behind using the sbc serp set-up & adapters. Cheaper, easier to source, lighter, & cleaner/closer (tighter) to the motor vs. the BBC set-up.

Thats a good find. It just adds up to way more than I want to spend. I was just thinking while I have the nose off and am doing a little clean up I would look in to it.

I had someone reach out to me with most of the parts Ill need. Just need to crunch the numbers and see if its the way I want to go.

I picked up a SBC serpentine set up for $50.00 Get one for a 5.7 and not a 4.3 and save your self a lot of trouble.

Why?

My set-up is technically off an S10 Blazers 4.3. Curious as the only difference I knew of was type of brackets (varied depending on year) & if they were equipped with or w/o a smog pump.

A member that has most of the parts I need reached out to me. All the brackets, New AC compressor, belt. I talked to Randy500 about it and he believed it to be a decent deal so I pulled the trigger with the member.

I have two pieces to order from kwikperformance and Ill need a reverse flow water pump for BB Chevy (which sorta sucks because I just bought a new stock AC Delco water pump). It was also mentioned I may need to change up the fan. Something Ill have to look in to.

You will need a reverse rotation fan. I measured my shroud & was able to get a slightly larger OD fan from Derale Cooling.

Ok that makes sense now that you said that. Thank You!

I have some parts you may find useful from my conversion to electric fans... leftover was the rigid fan, spacer+bolts...

It is a reverse rotation fan.

EDIT: free of charge if you can use it CG

Curious.... How was the alignment on your water pump pulley? Was it centered on the belt?
