Re: Serpentine belt conversion

Generally, either appearance or reliability. Or both. No doubt serpentine is better that V. But I’ve never been able to justify the high price of the “kits”. Unless you want to scour junkyards you’re looking at about $2K to make it happen.

I did it so I’m not chucking belts at 6k rpm. I didn’t go a full tradition serpentine set up just one belt to the water pump and alt. Then another to the PS pump. Both serpentine and I think they were march performance.

That price would be reflected in a kit for a which comes with AC, even then it might be too high of a guess.

Shop around, March makes some nice kits, the are other brands out there too. Prices and are quality will vary. Cheap Chinese kits would be wise to avoid.

Re: Serpentine belt conversion

I spent $150 on complete serpentine kit and T.B. Intake, unit and computer, distributor, alternator. All from 1990 Silverado with 5.7. I did it for drivability reasons, it is not pretty, but cheap and extremely functional. Downside is (afaik) all are long water pump setups, so account for that. If staying mechanical fan, you need a reverse one of those, and a different water pump for reverse (I still debate that to an extend if you look closely at the impellers, they mainly force water out, not around, and if they spun the other way, out is still out...).
Also with P/S pumps that are with anything remotely modern (last 30 years) they use the O-Ring fitting, so a great time to do the JGC Steering Box swap, and just use all modern hoses.
Plus the pickup system, has an a/c delete pulley option, so you if add it in later (like I did) nothing new is required, not even the belt. Plus the newer alternators that are with them are much better than the old ones. My only issue is pulley alignment, primarily around the p/s pump. I think that there are different pumps/pulley combos that seat at different depths. Also, on my setup, the A/C is high near the passenger side valve cover with the alternator on the other side with p/s pump under it. It can make running a top hose complicated depending on rad outlet location.

Re: Serpentine belt conversion

To answer the first repliers question. Reliability and clearance issues. Maybe a tiny bit looks but also a bit of a perfect storm, 50 year old power steering pump tired and leaking, been needing to be addressed for quite a while. Water pump weeping for a while, and my alternator went out yesterday. I have to spend a few bucks addressing all this so if there is ever a time to do it, it is now. It’s a new 502efi t56 super magnum combo I bolted all my old 454 💩 on when I swapped it out.

Re: Serpentine belt conversion

I don't know if the brackets are the same for SB and BB. If they are, I recommend getting a set from an early 90s Camaro or Firebird. As said earlier, the pickup or full size SUV brackets will work but, they're taller than the car units (and uglier). I went that route on my 83 Camino (initially) but, when I put on a larger alternator, the pulley rubbed a hole in the under-hood insulation. Also, as said earlier, you will need a reverse flow water pump and, you will need a power steering pump for the serp equipped Camaro/Firebird brackets. The basic PS pumps are the same but the filler necks are at different angles and the non-serp PS pumps will not fit into the serp bracket.

There tons of aftermarket kits on EBay in the $300 to $700> range and there are usually a few used sets on EBay as well.

Re: Serpentine belt conversion

I did mine for under a $100. The billet ones will cost you about $2K as stated above. Came off of a mid 90's truck and is the same one offered in the GMPP book for a fraction of the cost. There are several different models from that era. One has what appears to be some air pump bracket low on the passenger side and is quite ugly and bulky. I powder coated mine black after cleaning the casting flash off of it. There was an article written by Jeff Smith in Car Craft a few years ago that explains all of the differences and how to make them work for both SB and BB. Do a search and check it out.

I bought a chrome power steering pump and polished A/C compressor. Wife's happy now, and that's all that matters.

That is probably the one I have. I cut off the Air Pump bracket part at the bottom of the passenger side mount bracket. It was interfering with my manual fuel pump. And it has 2 holes for the idler pulley, you can move the idler, and route a belt without using the Air Pump.

I did the Billet Specialties Tru Trac. Really impressed with every aspect of it. Not cheap, but quality rarely is.
