I have a 98 S10 step side short bed / L33 5.3 with LS6 intake / 4L65E and 3:42 8.6 rear-end. I'm looking at Holley # 20-131-BK and installation kit # 21-3. My concern is with which water pump can I do this without moving my radiator forward?
Yes they are, I am considering the full Holley high mount AC system my self. By the time I locate all the crap that will be needed... I might as well order the whole damn kit. I am looking at the mid mount system, part # 20-185. It's on sale for Christmas... only $1600, MERRY CHRISTMAS TO ME... divorce court next month...Are the Corvette crank pulley and waterpump extremely expensive? Otherwise why wouldn't you just go with the shortest . setup possible to allow more room for rad and fans? Or does it require Corvette alternator and PS pump also?
I'm thinking of going Vette on my LQ9 unless it's too pricey.
Is your swap done and you're adding AC, or are you still working on the swap?Maybe I'm not reading the Holley criteria carefully enough but will the #20-131 brackets work with the 5.3 R4 compressor, power steering pump and alternator or are they specific gm units?
the new replacement compressor I got (after I turned in the POS rock auto ones) is a improved 10 cyl one thats fixed that seal.Ls swaps never come in on budget.
I don't think Holley offers a kit for the stock (Leaky Tiki) compressor . They offer both Sanden and R4.
If your stock compressor is off for any time the seals will dry out and you'll need to replace it anyway.
Who ever thought up that design with seals in the middle of the main housing didn't do anybody any favors.
Buying anything other than Genuine Sanden is an absolute waste of money, period full stop. The price has come down, you can pay 100$ for chinese crap, or do it once pay 200$ and get the real deal. Same goes for those ebay water pumps, avoid those suckers like the plague unless you want a breakdown on the side of the interstate... AC Delco Genuine Waterpump is the only thing that should ever be bolted to an LS, anything else is just asking for trouble.the new replacement compressor I got (after I turned in the POS rock auto ones) is a improved 10 cyl one thats fixed that seal.
we will see how well it holds up,only been a month so far.

but it does come with all the bells and whistles and bolts. $2000 normally, I'll build a few more transmissions to pay for it.

With the brackets 20-131 and about a half dozen other components it runs the price up and you still have the high mount with the truck wp and used ac, alt. ps pump. I might just bite the bullet and get the mid-mount kit...everything there and all new... Like you said when I first started this project," there is no cheap LS swap unless you are willing to do tons of work and even then it's not cheap.Ls swaps never come in on budget.

I've read the component require with brackets 20-132 list / price. Think I'm going to go with the mid-mount accessory kit, everything's there and all new. Plus, more clearance hopefully better routing for air intake etc. At this point I have some money invested in this project, would hate to end up with a half-*** mess over a few more hundred dollars.The notch for A/C is an interesting topic... I considered it at the time when I was doing my swap, but a few unknowns stopped me from doing it. That and I hadn't done enough research regarding header clearance/fitment (though those new cast iron blackheart manifolds look like they'd be the ticket). The down low compressors are smaller displacement and that means weaker A/C. The upside benefit is using a separate belt, tensioner and the back set of grooves on a Vette Crank pulley or a truck crank pulley. I'd think the vette version would be better since face to the compressor is 1" less projection. It has and can be done its just more diy and research for anyone really wanting to do it. Oh and making your own A/C lines as nobody sells a swap set for that, however all the parts are available at coldhose.com
FWIW... all Holley kits use the same components.... The only difference is the mid mount includes 1/2" spacers added behind the bracket for mid mount, and 1" spacers for long/truck mount.I've read the component require with brackets 20-132 list / price.
