Hot Rods 383 Stroker - Overheating - Water Pump?

This is a picture from NAPA of the 58-134.
Do you need more bosses than this pump has?

 

Well it looks clear you have the wrong rotation pump, I think I would spend the 20-40 bucks for standard old school SBC brackets at your local wrecking yard and get rid of that late 80's hybread gm mix up.... era stuff....

 

The boss that's been a problem is the top one next to the heater inlet port. I was sooo close several pumps ago with a new 43-101 (I think). It's a std rot, but didn't have the top mounting for the alt bracket.

As far as using this belts system, yeah if I new it was going to be this kind of a problem I'd have trashed it in the first place. I've got a full serpentine setup from a '89 (where I took the block for this motor). I was putting this system on because it'd be 'easier' and the '89 system needs some reconditioning.

 

Same reason I went to my local salvage yard and found a GM vehile that used v-belts(86 may have been the last year). I took everthing I could off the front of the motor( all the brackets,pulleys,etc). The good thing about doing it this way is when you need an alt( or belt,ps pump etc),you can go into a parts store an order exactly what you need knowing it will "bolt right on". Hopefully the pump you have ordered will get you squared away.

 

Here is another picture of the 58-134. Isn't there a boss next to the heater outlet?

 

I thought I'd conclude this thread: The problem turned out NOT to be the water pump. Somehow, someway, I put the intake manifold gaskets in backwards. Man I hate it when I'm stupid! It took an independent person to look at the motor to make the diagnosis as I would NEVER have thought I'd do this and would never have thought to look...until a few more weeks down the road of beating my head against a wall. It just goes to show me how stupid I can be...lesson learned...once again.

 

this may be a stupid question but are the intake gaskets on right ? i had a customer truck that overheated , the customer had installed a new long block himself , when he put the intake on he put the intake gaskets on backasswards , the restrictor goes inthe back . if they are in front you only have 1/8 inch hole for all coolant flow

 

oops didnt read far enough

 

Not to Hijack a thread but, this falls in line with a question I have...and seeing how the thread cooled off about two month's ago...:>)

I just picked up a new crate and a new Edelbrock intake. In the instruction to the installation of the Intake, no mention is made of center port restriction plates.

However on the installers guide for the crate, they make reference to the center port being restricted with the "metal plates" supplied...

I'll be hooking up a 4B to the intake...

What gives with the "plates"....any help would be appreciated

 

The metal plates, in the center ports, restrict the flow of exhaust under the carb, from the exhaust crossover passeges in the heads.
On earlier engines there was a valve on the passengers side exhaust that would close when the engine was cold and that would force some exhast to "cross over" under the carb to heat the carb for cold start driveability. Over the years manufactorers started limiting the amount of exhaust crossing over.
Most current heads don't even have crossover ports because there is no reason to heat the manifold for fuel injection. The computer handles the cold start driveability.

 

had a buddy that battled overheating on a big-block chevy for months. He was running underdrive pulleys. Switched to regular pulleys after trying everything else and solved the problem. Just something else to note.

 

They have the information about the rotation of the pump on the computer and in the book. I don't work at NAPA but I do work with the parts guy when I go in because I always have off the wall stuff to work on.

Here is another trick call Summit racing or go to their site and look up an SBC reverse rotation pump. Tkae the part number and remove the SU or SUM from it. that will give you the proper part number to take to the NAPA store with you.

GM used reverse rotation pumps in the later '80 when they went to the serpintine system. You may try looking at a camero with a serpintine belt system. if the NAPA guy doesn't know what year have him look up the belt first when he hits a year with a serpintine belt you are golden.

 

make sure you have your thermostat removed. you can easily determin the rotation of the pump fins as related to the rotation of the belt.
