Re: water pump drive vs electric pump
 

I'm with you, but I already had one as a spare for my super gas car so I used it on my 305 station wagon. Busted off a smooth -.19 12.80 with a race water pump lol. And the one I have is a CSR I bought new for like $130.

I got the pump drive all installed and then to wire it, decided to run a 30A in line fuse and a relay to power the pump and the electric fan. Both on or both off, not sure if I'll like that but there it is.

Relay on right shock tower,

Personally, I always run the water pump separately from the fan. When you are warming up a cold engine, no need to have the high draw of the fan going, slowing down the warm up. Plus I don`t run the fan going downtrack, blowing hot air back towards the carb.

We use the blower motor belt pump on my boy's Stocker and it
cools as well as my aftermarket pump and electric fan.
Plus it draws less than 1/2 the amps even running the fiberglass fan
than my Pump/Fan setup.

We have aluminum Radiators on both cars. Perhaps the aftermarket
pumps circulate to fast?

I'm thinking I'll change it, not sure when. It's operating now, fine tune later.....does that sound like I'm rushing?? lol.

I had a 2 speed motor from the junk yard but dang I can’t remember what it was off of. Just make sure it has a 1/4” shaft, I even sourced the cog and belt from ‘Mr Gasket’ then made a simple aluminum bracket. Never bought one new in over 50 years. Go to swap meets there’s usually 2 or 3 on a table for 10 bucks.

5/16" shaft is what's needed.

Even better, had a local Stocker guy that had a spare he could let go for a good price!
