If it is going to be your daily driver I'd go with a 351 Windsor and an AOD ******. About some 373 gears, late model Mustang seats, air, tilt, and cruise. My Son has a 5.0 with AOD and 373's that runs strong, rides good, and gets around 20 MPG.
there is no subs***ution for cubic inches build it big bild it strong and only use half the peadl and it will go for ever
I gotta go with Fat Hack on this one...351C with 2 barrel heads and aftermarket 4 barrel manifold with a top loader. Winds like a 301 chevy with more torque...exhaust sound is unbelieveable. Or put a...........nah, nevermind.
