I'm not concerned abt lack of htr conn.
I'm not sure of the lack of by-pass outlet.
How important is the by-pass??
Anyone care to comment?
I'm still looking at all options to solve my lack of space problem.
Does anybody have opinion on this water pump?

Bypass is the only thing that allows circulation of water in the block before the thermostat opens.
Without it, it will take a long time for the thermostat to get up to temp. And all the coolant will be stagnent in the block till it does.
You might be able to create a functional equivalent?
What are you working on?
My 360 based 416 stroker in my 67 Barracuda.
I have a very expensive rad/shrd/el fan combo that I really want to use. But I lack 1/2 inch to clear wp pulley. And thats with NO mechanical fan. Just the pulley.
I can put a slim mech fan but cant use shroud with it.
Only have 2 1/2 inch from front of wp to rad!
Looking at all options.
Don't know how to plumb a connection for by-pass into this wp.

Is an electric water pump an option?
The ones I found took up even more room!
Plus very expensive and no by-pass provision.
I just ordered a mech fan that I hope will solve problem.
Looks cool but the factory fit SB and BB in there with mechanical fans and no clearance issues. And no overheating issues!
IMHO
The aluminum rads are over rated and just cause more issues than they solve.

'91 Dakota 318. Only issue is it requires a Magnum-style timing cover (which also means no provision for a mechanical fuel pump). It was still v-belt driven, so rotation is standard.

Standard pump:
You're on your own for pullies/spacing, maybe try to find a '90-'91 Dak V8 in the boneyard.

Easy. Forget the bypass. If you have that pump and it will fit, you don’t run a thermostat. You must run a Restrictor. You can gut a thermostat so it’s just the open hole or buy (Moroso iirc) or fabricate a restrictor. You can adjust the diameter of the hole (make various ones/buy them in a set) trying various ones to find the size hole best for your setup.

Very interesting.
What’s the reason that this pump requires a Magnum timing cover?
Thanks

can't you just use a restrictor instead of a thermostat?
looks like someone beat me to it.

The Dak pump is an early version of the Magnum equipment, only standard rotation. Used on the LA due to space restrictions in the Dakota engine bay.
These pumps (and the Magnum pumps) had a wider spacing on the bottom two bolts, and a slightly different mounting surface shape than the standard LA pumps and covers.
[1] There is NO reason not to run a stat. It will give some temperature control, get the engine up to temp quicker. An engine that is at operating temp will use less fuel, perform better & last longer.
[2] If the pump has no bypass & a stat is used, the stat needs three 3/16" holes in it. Not mentioned so far is that the bypass also acts as a pressure release if the stat fails to open.
[3] Most important thing to check for pump efficiency is how close the spinning impeller blades are to the fixed housing. Hard to tell from pic, but looks close, & closer the better.

Gosh, the bottom hose inlet sure looks mighty small.

Bang em till it breaks
I have this pump brand new in a box still havent ever used. I hate the inlet design. Mine doesnt thread in even remotely close to what the OP photo shows. Im scared to even put thread sealer on because of how tight the fit is that it will crack the housing trying to tighten the neck in there... Extremely nice pump itself very well made and nice finish. I run moroso restrictors and no T stat. Even with stock style water pumps but I just haven't bolted this pump on to try yet building 2 more small blocks in the next year or two and will try it on one of them. Best input I can give you as of now.
