302W = 5.0L motor as seen in Mustangs throughout the 80s and 90s. Just a different name.
Cameron - don't you just love the sound of the B&M blowers when they start making boost !!! I had an old Cortina with a B&M 144 on a 302W and LOVED it.
Stuart - you running fuel injection? If so, I'd look at using a Vortech centrifugal blower. I chose that brand for my car based on the results being achieved by the Mustang guys in the States, and I've been happy with the performance and most importantly, the reliability of my blower. For a mild motor, you would probably want to look at something like a Vortech V2-SQ supercharger for great results. Oooohhhhh... that's a coincidence - I have a spare low mileage one sitting around in my garage to suit an AU 5.0L motor, complete with EECV computer chips, high volume fuel pump, brackets, pulleys, belts - the lot.
