Default M/T crossram intake for 65-later heads?

Does anyone know if there was an intake for '65 and later heads? Or maybe somebody else besides Mickey Thompson made one? Anybody have one? Photos? For sale?

One of those 303 RA4 head intakes would be perfect since I am building a 301/316 stroker "326"... but wayyyyyy out of the budget for this build! But now you know, as did the Pontiac engineers, why I want one or might build one from scratch.

This will be for a short deck engine, so it will be modified anyway.

I have a converted M/T but not going to part with it! Flowbench numbers sucked but has the cool factor for sure.. Will probably go on a motor for the 65 GTO project.

Here is my M/T crossram. (not for sale) It has all of the early water manifold removed, and I plumbed in a remote thermostat housing. The alternator didn't clear the front runner, so i moved it to the passenger side.

for your intake Tom?

I have one of the Modded for 65 & later heads but it would not be cheap.
I have over $1,000 in the welding and other mods to make it work for the later heads.
Then you have the M/T crossram cost above that.

IT could be bought but not cheaply.

Pontiacjeff, My crossram intake is identical to Dr Skip Fix intake as we did mine before we did his (shown in the pictures. Balance tube, lower part of runner flanges welded for lower port placement on 65+ heads. Water cross-over modded for ability to properly allow flow on 65+ heads with existing crossover. Mounting holes in cross-over changed to 65+ location. You can see how we built up the runner wall thickness on Skips intake runners to allow the intake to seal properly to the later heads.
