w a 455 youre likely to have hot issues....radiator in these are smaller than the cars that had 455s...it CAN be remedied, but my friends who have them , have lots of issues...300 should be fine...
Yea it could be problematic. I'm considering a resto mod with a LS i'm not sure. The car is done with the exception of the drivetrain. What would be a estimate of the cars value after a LS swap not wanting to sell it anytime soon might keep it forever, it would just be a great base for a car would be reliable and i would get more power with a base motor.
all depends on the values at the time ,and the 'correct value' will be depending on buyers wishes...if he wants an LS, you might get more, if he wants 'original' , maybe less...value is always based on agreed price between willing seller and willing buyer...
