I purchased a 1965 mustang fastback about 3 years ago since then I have rewired it completely as well as a complete stock suspension replacement . I just finished a 331 stroker 405hp 375 tq install along with a TCI c4 street fighter trans and 3.4 -1 rear gears at around 90 mph the front end seems to lift and float any ideas on how to correct this as I haven't really tapped into the engines full potential yet this was at around 4300 rpm thanks
