This may seem a bit odd but does anyone know if there is any possible way to install a 6 speed transmission and a 426 HEMI into a Cadillac Escalade EXT? That truly is the car of my dreams!

If you have the money and the will, I'm sure you could do it. It'll probably take quite a bit of fabrication...

Honestly, I don't think you would be able to put a different engine in it or a different tranny. For one, the HEMI is made by Chrysler Corp. while the Escalade is made by GM. The Escalade has a 4 speed transmission I believe and it may be easyer to install a 6 speed in it. But the HEMI V8 is adefinate no-no. You could MABEY get one to work, but it would cost so much for the engine and fabrication that you you would have to be insane to actally go through with it. If all you want is the 425 BHP, install a turbo/supercharger or a cold air intake.
