just remember it has to have mass air to do heads and cam. it wont run right if its still speed density. so check to make sure it has it. if not you need to do that.
Ebay my freind....I just did a quick search under Mustang Suppercharger & found a Powerdyne 6psi for 1599.99 New with free shipping & 3 yr warrenty & a Vortech SC trim for 1649.99 new. You can find used ones for less than that. Hell, I only paid $280 for my Edelbrock Nitrous Kit on Ebay new. If you search around you can do a blower, gears & exhaust or H/C/I for under 3 grand. just reseach your seller's to make sure your not getting scammed. I built 80% of my car with stuff I bought on ebay.
