Digging up the p pump again

[Austin86250]

With the recent digging up of the p pumped 6.9 again on Facebook I just find it completely fascinating and google can’t seem to bring up much so I’m wondering what y’all know about the hypermax idi build from the early 90’s

His grandson came to the forum not long ago and posted more pictures and some details. I messaged him if I could film an interview but he disappeared from the forum. He mentioned he wanted to bring the truck back to life.

Maybe you just gorilla glue the block to the heads for 145 psi

Also maybe a few ratchet straps to hold them down too

Jesus, it looks like someone strapped a small 4 banger on top of an idi

I agree I hadn’t seen that before and it took my brain a few seconds to sort out what I was seeing.

Is that your build?

 

[IDIoit]

Is that your build?

yes.
covid hurt me cash wise, so i had to stop the build.
sold the rotating assembly which was crower rodded.
but i still have the gear and the pump.
when i have time, ill make a mount for the pump.
i also have flanges for a intake/valley as the factory one wont work with a P7100

the engine you see is girdled, and decompression, but is going into my 63 ranchero with twin turbos

When that guy was on the forum, it got mentioned that the cylinder walls would actually flex out a bit.

It's clearly a small straight-8 on top of a V-8 IDI, geez can't you count?!

I want to see the intake manifold you will be making!

It seems like welding would be a better choice.

Yeah but how would you service it then?
