Radiator/airflow issue.



I'm still working on that issue (31" aluminum radiator, mechanical pump and MP viscous fan setup with full shroud; I used to have an electric pump and dual 10" fans, which were too small, I'll be back to a big electric fan setup this winter).

what is your initial timing at idle.


Don"t know fur sure (my timing light gives inconsistent readings below 3K RPM with the MSD, I just dialed in 36° at 3500 RPM).
I'll try to check today.
