I’m in the process of trying to figure out how I can my old LS GTO torqstorm supercharger on my 5.3 in my 78 vette. I can physically bolt the supercharger in but running into belt issues. The belt runs directly into the upper shock stud and then the waterneck becomes an issue.
im wondering if there is a low profile SBC style waterpump that as the lower outlet like a SBC that fits the LS? I have the slimline speed master electric pump but I don’t want electric for the street and then would have to figure out belt routing. Car is street only and I really want a mechanical pump.
I have to use a straight waterneck due to the upper control arms on the C3. To route the supercharge belt over the waterneck would require some interesting belt routing and a new pulley system.
Not a very cost-effective solution but you could always do a remote mount Davies Craig pump mounted to the radiator and then do AN lines for coolant.
I've got a Davies Craig setup on my current car and it works fantastic.
My water pump isn't mounted to the radiator but its down low in the lower hose supported by the hose.

I thought about them, I like that they can hang off the bottom rad hose too. My lssue would be the belt routing as I would need to figure that out without a WP pulley. I could likely make the alternator adjustable and become the tensioner. THen I would need to figure out pump mounting which is going to be tricky as the rad has a upward 90* outlet in a very tight space. They only flow like 55GPM right?
They make swivel inlets, not sure how it would work, I have also added fixed idlers to reroute belts to clear things.
yea I have a mr gasket swivel style for an LS1 pump that I could try. I did put a lS3 Camaro pump on recently to gain more clearance for the upper hose. I would have to find a swivel mount for the LS3 spacing.
I would have to figure out at least one pulley near the shock stud to route the belt up and over the arm. I can’t mount to the frame as the engine has poly mounts currently. So it would need to be built into the bracket or engine side in some way. Either way 3/4” billet is not cheap so I would need to mock it up in plywood or MDF first. Speed master makes a HV mechanical pump but still have the same issue with the belt and no tensioner mount.
I didn't provide any links, just pictures. Are you talking about the link in my signature, to my Turbo C3 build? That works fine.
I also had water pump and upper control arm clearance issues in my boosted C3. Ended up going to an SPC upper control arm to gain back some space. There are no alignment shims needed and the shorter bolts can be put in backwards for more clearance. Don't know if that will give you enough, but it gave me plenty of room for the heater hoses.
I know firsthand that shoehorning boost into a C3 is a tall order. Had to get rid of the Rad support, get rid of the whole vacuum system for the headlamps, and modify the hood hinge to get clearance for the rad and the intercooler. Worth the effort to make it stock looking.
BTW, on your supercharger exhaust, it looks like it's going to go through the hood. Can you clock that?

Oh, the pic didn't show up for me and when I clicked the link it said it couldn't be trusted.
I have the SPC upper arms already, they gave me more clearance for the supercharger body which hit the stock arm in the middle with the car at ride height.
Supercharger exhaust is clockable but I'm going to cut that off and route it back towards the firewall. Then I will hook it up to a A2W intercooler and a heat exchanger up front. I also have already converted to electric headlights. Heater hoses aren't a problem its the actual supercharger belt runs into the upper arm cross shaft and the front shock mounting stud. I need to loop it up and over to clear which means a pulley on the underside of the supercharger where the arm is. I don't know if thats feasible yet otherwise I need to make all new brackets and reposition the supercharger up and intowards the engine to help with the belt issue but then I run into possible issues with the hood. I didn't test but it might clear the stock hood as is once I redo the supercharger exhaust. I also have the LS3 pump on the car already which moved the upper hose out of the way nicely but for me now its the waterneck. I haven't tried to mock up the supercharger since I did the LS3 pump though.
Not sure what they flow but it has kept my car cool in all conditions, even going down the highway at 60 mph turning 2,600 rpm on an 80 degree day.
The pulley arrangement will take some thought, the picture attached isn't what I currently run.
I had to add an idler above the tensioner because at high rpm it would toss the belt.
Plus I don't have P/S either, just runs the alternator.
