I have a 1982 mustang with a fresh 5.0 and 5 speed in it. I haven't been it anything sporty for a long time. I get nervous driving my car because it seems really fast and its loud. I cant think when I driving it. It doesn't seem like it should have more than 250 hp. Here is the specs. ford 302 with explorer gt40 cylinder head, edelbrock performer intake, crank scraper, 226 duration with 466 lift camshaft and headers with flowmasters. How much hp is this combo? Im running no accessories.
