66 overheating and pinging
Help! i just had the motor rebuilt. the rad is clear. my mechanic is trying to tweat the timing. the transmission is 2 speed. while idling and driving up to 60mph, it runs great and heats up to say 210degrees F.
after 60, if i try to push it harder, i get the bag of marbles sound and the temp starts climbing up to 250 F or higher. my mechanic says if i switch to electronic ignition it might help, plus it will be more reliable..?
any one have any thoughts on this issue? do you agree with him, and if so, any suggestions on what type to install?
