I have a flowkooler water pump that im trying to use with my bbk underdrive pulleys off my serpentine set up for my 92 tbi 305 but the holes for the bolts dont line up with the waterpump holes. The waterpump is for 85 to 87 camaros but i dont think there is a differnece in the bolt holes between years. I was wondering if anyone was running one of these and which pulley they used? Its part number 1773 pump.

 

didnt the 85-87 have v belts?
I had the same problem with my flowkooler pump... i ended up using a stocker from autozone that works good.
or if you have a drill and a tap set you could just mount the pulley on the pump and use the holes on the pulley as a guide to drill and tap some new holes.

 

stock v-belt or a serpentine pulley?

 

I believe your `92 is a reverse rotation set-up and the 85-87 are standard rotation. The two don`t mix, don`t interchange. The 1773 pump will fit earlier models, you need the 1774 for your `92. I had the same problem with my Iroc.

 

thanks for all the help. I guess ill just have to break down and get the other pump. Good news though, i got the motor fired last night for the first time, open headers too. All I could do was smile!!!!

 

yea its a good feeling seeing all your hard work pay off.... mine was timed 180deg out the first time i tried to fire it and big flames shot out the drivers side header... couldnt figure out what was wrong but it was 2am and i was half dead lol.

 

matts, I got a lot of conflicting info from Flow Cooler, Summit and Jegs about the 1773 pump and decided to go with Stewart. If your car is `88 and up with the serpentine belt, you for sure need the reverse rotation pump as I said before. A Flow Cooler tech told me that the 1773 was multi-directional, would work either direction. Summit said yes, Jegs said no. Play it safe and get what you know is the correct part.
