Armondo-
You may be able to retard the spark a little and eliminate the ping
(assuming it is ignition ping/knock and not a mechanical (bearing)
knock. Retarding the spark will reduce performance a little, but
thats better than etching pits into the tops of the pistons with
routine pinging.

My 63 +4 is tunned to specs and runs fine except under heavy load
(like when going up San Francisco hills). Then it starts to knock
its head off. I use 92 octane gas, the highest I can get around
here. According to other web pages, a 9:1 compression engine, like
the TR3 is supposed to be, requires 96 octane gas. Has anyone solved
this problem? What about additives? Are they any good? Web wisdom
appears to be that they are a waste of money. Any suggestions?
