Hi Glen,
I know this is a dumb question, But what is your Timing set at? I had
problems when timing was off.
Strange but Puddles doesn't over heat at all, and you know how much
engine work is in her. Only difference I can see is I'm running a water
pump plastic fan. It's out of a 71 Midget.
If it is still happening, they make a core for radiators that is a
higher efficiency. It has more baffles or some thing. We use them on
MGA's as they are notorious for over heating. Maybe this would help.
