Ok, so I pulled the heads on my '65 289 and found a couple things that I mostly already knew. The #4 cylinder has scoring on about a quarter of the cylinder wall from a broken spark plugs bits. Thus why the car has been sitting for 12 years. I also found a 60 on top of the cylinders indicating that my grandfather did indeed bore the motor. Now, everyone knows a new crate motor is sweet and a little costly but from y'all experience what am I looking at, cost-wise, to rebuild the numbers matching motor and am I just beating a dead horse trying to get this motor to be trouble free? My goal for this car is to eventually have a smooth running reliable car that I can take down the road a ways. I don't want a hotrod but I want a stong motor and eventually disk brakes and a T5: the classic look with modern, bolt-on, drive ability.
