water pump bypass LA intake on Magnum

[mcm95403]

I'm looking at getting a strip dominator modded for MPI use on a 318 Magnum, but wondering what can be done about the bypass hose port not being a direct match-up for the Magnum water pump port.
I'm guessing the t-stat outlet won't be as much of a problem, but not much room to work with the bypass.
I'd use EQ heads with the LA bolt pattern to solve that issue as well.

Engine builder screwed a plug in mine. Says it's no big deal.

First I've heard of that.

It is no big deal as long as your t'stat doesn't jam shut. If that happens, the weak link to relieve high rpm coolant pressure are the freeze plugs, & one will likely blow out leaving you stranded. The bypass also shortens the engine warm up time, important if you live in a cold climate.

If you block the bypass, use a t'stat has three 3/16" holes in it. This provides pressure relief when used where the factory bypass has been blocked.

If your car has a heater core, it can be your bypass.

Make sure those heads have been corrected.
New EQ Head port misalignment?

I agree

I agree

I am running a heater core and A/C from Vintage Air, although with their system, the water flow to the heater is either fully blocked or partially blocked depending on the control setting of the unit.

I'm going to drill 3 - 3/16 holes in my thermostat to ensure enough flow to compensate for blocking that bypass hose on my engine. The plug is hard to see, but if you are able to zoom in, you can see the edge of the plug in front of the thermostat boss. There is no path for the Bypass hose with the Factory Magnum A/C bracket.

What intake manifold are you running?
