Snowman, is that Tom’s exhaust manifold?
I’m seriously struggling on whether to pull the lane 350 from my 55 Belair and replace it with a built 250 w turbo @ 15psi!

Mick - the Mazda Millenia used an air to liquid intercooler under the supercharger... I would think you could do a draw through supercharger and force the pressurized mixturethrough the cooling fins without an issue.
But, IMHO, I’d be going with meth injection. Nowhere as reliable, but far less complicated!
