1994 “cooling fix kit” 😁

Now we're using the Ipsco plate. check it out. click the link below.

He has lots of Pantera parts, & he makes them all. Good people to deal with. Check it out:

Pantera Parts (ipsco.org)

Agreed.

Mark Johnson at IPSCO is a one-man operation. He is easy to contact and will work with you on custom projects. He is the machinist who has created most/all of the custom aftermarket parts sold by Dennis Quella  

Mark was the first to have the overdrive water pump pulley, which another vendor initially sold but that vendor then decided to have his own pulleys manufactured by some other outfit. 🙁

It says the IPSCO block-off plate is designed to REMOVE the thermostat?  Really?  Can some one elaborate?

❓❓❓

I am also confused.

I have not known Ipsco to manufacture a OEM replacement thermostat restriction  plate. The only offering from IPSCO is the total block off plate you found.

if Sharky is using the total block off plate I think now is the time for him to step in and explain why he is deviating from the OEM cooling system design. 🤷‍♂️🤷‍♂️

Tim Meyer is the current and reliable supplier of his OEM-design restrictor plates and the correct high flow Cleveland thermostat

Larry

We buy the correct RobertShaw restrictor w/thermostat sold as an assembly to use. That being said, you can expect the same results with Marks plate & standard 54mm Chevrolet thermostat.

Your choice. Does the same job.

Thermostat Block off Plate (ipsco.org)

ok so the IPSCO block-off plate does not OMIT the thermostat it just blocks off the by-pass?

…..We buy the correct RobertShaw restrictor w/thermostat sold as an assembly to use….…….…..

……Now we're using the Ipsco plate……

So confused.

your first response indicated you were using the total block off plate, and then you posted you were using the Robert Shaw OEM plate and thermostat

do you buy the restrictor with thermostat from IPSCO, because I don’t see it on his website?

if not, is your source some one other than Tim Meyer??

inquiring minds want to know😉

Larry

"ok so the IPSCO block-off plate does not OMIT the thermostat it just blocks off the by-pass?"

You still need a thermostat yes, and if you see the item in question it is not a total block off. That's why I said use the 54mm chevrolet thermostat or the Robert Shaw [also 54mm].

'your first response indicated you were using the total block off plate, and then you posted you were using the Robert Shaw OEM plate and thermostat'

I never said I used a total block off plate.

I use either. Both work.

Ipsco does not sell Chevrolet thermostats you can buy them anywhere. He makes the plate I sent the link.

My 1974 Pantera came with the no hole plate along with a Windsor thermostat.  It was the first Pantera for me with this setup.  I left it in place and all is well.  The car runs cool.  The downside to this setup is the engine is supposed to take longer to warm up.  Strangely, I have not found that to be the case.  The car warms up just like other Panteras.  I'm in southern California and maybe it is different in a colder climate.

What is the manufacturer of the water pump you are using?

Larry

I'm not sure which water pump is on the motor.  I would have to take off the covers to find out and I can't do so at this time.  Some of the pumps do not have a port for the coolant bypass system, correct?

Correct- the popular Weiand pump has no cast passage, and others either have no passage, or have been blocked off with a shim or a non-stock gasket. A lot happened in 50 years.....

The Wieand pump is easily drilled with 1/4" bit.
