When I was about 22 I had a 63 falcon futura that had a 64 fairlane 289 2 barrel and C4 in it when I bought it, I freshened up the motor, slapped a performer intake and Holley 600 double pumper carb and a HI Energy 268 cam, oh boy talk about waking a sleeping giant up. That car was scary fast. It had 323 gears and would not spin a tire, I ran off and left most everybody at the light, if I remember correctly it ran low 13's in the 1/4 with no other mods and a old point type dist.
Just make sure to upgrade to the stiffer valve springs though.
