Okayguys, some of these questions may sound stupid, You must forgive me I just became a mustang enthusiast. Alright Lets say I have a 92 mustang Gt with a procharger running 9lbs of boost, however I want to put a 351 in the car rather than the stock motor. Can I easily swap the supercharger over to the 351?. Also will I have to buy a whole new wiring harness for the motor or can I use the stuff from the 302? Bell housing the same?? Would the swap be worth, performance-wise it if I built the 351 to handle a supercharger? If you guys have any input that would be great. I want to make a really bad street car that is somewhat dependable. --- I am a rookie so anything will help. Thanks for your input

 

Let me start by saying that htere is no substitute for cubic inches except cubic feet. So YES the swap would be worth it.
The 351 is taller so you will need a fuelie 351 intake manifold. The bellhousing is the same. As for the supercharger, not sure what you would need. Could be a direct bolt on or you might need a bracket from the manufacturer to make it fit.

 

you'll need a lower intake, your upper will work. the bell housing will work. Yes the swap will be worth it, and i dont thin kthe 302 mounting bracket will work with the 351, i don't think it'll fit under the hood. Build the 351 with some forged internals anda high cobustion chamber head 64cc+ and a lower compression piston and BOOSTthe hell out of that thing. the block will hold about 600-700 hp so have fun with it. Also be sure of the other upgrades that are needed with more power (fuel, suspension, trans, rear end, chassis and brakes). Have fun with it and be safe.
