Yeah, I guess you did it.
It's quite a contrast with my limited high speed driving experience though. [link|http://z.iwethey.org/forums/render/content/show?contentid=105895|#105895]. That engine had 350 gross HP when new, probably over 200 at the rear wheels even at that time. It would only do 120 mph max and had a 140 mph speedo. It had a 3.23 rear end, so the gearing wasn't an issue.
I find it hard to believe that a stock 1982 4 cylinder Mustang had that much power. Fess up, you were running nitrous, weren't you. ;-)
Cheers,
