273 or 318?
64 GT ide have to go with the 273, if its a 66 motor its a solid lifter cam motor,,probably a forged crank,, get a set of commando pistons from EGGE,, and a hypo cam a intake from offenhauser,,you would have a high reving little monster a hy po 273 will surprise you,,,get low 1st gear tranny,,,would be a fun car to have,,, ide love to have a 64 GT WITH A HOT 273 but as stated,,the price sounds high,,,but he may know what he has,,,a vintage mopar engine thats dissapperaing,,
