Yes, you can install a Roots blower on a 4.6L. Installing one from a 3.8 SC would not be easy and expensive. If you want a Roots kit then look at the AED, Sally-een (saleen), Kenne Bell (soon) and SVO kits for the 4.6.

You don't need forged internals with the AED kit but it would be a good thing to do when adding any type of forced induction to a stock motor. Read the articles in the tech section regarding the AED kit install for more info. A bunch of guy's run them here without any issues other then the fact that the Alt is backwards. I would start with the 6 PSI pulley.

When I ordered the 9psi kit from allen they said that I may blow my motor. Running 6psi on a stock motor is fine, 9 is really pushing it. My motor is still stock no PI heads nothing. When I blow it I'll have it rebuilt from the ground up, stronger then ever.:D But until then I'll press my luck!

Just do like i did find a guy with a mustang thats upgrading and get his old 4.6
You "can" use a Vortec or a paxton blower but I would say the vortec is the better bet after doing mine.

In this case you will not be able to walk a z28 and get good mpg. Just aint gonna happen (Or at least I don't think so). Sorry

Try a Turbo? The power comes off of the exhaust gases, which are basically doing nothing anyway! A supercharger uses a belt driven off of the engine. Of course, anytime you put your foot into it to beat a Z28, you're going to use lots of GAS!!!:D

By the way, good luck in your quest and let us know when you kick Z28 A**!
