over heating
I had a 1976 340 olympic it was fan cooled,
but it ran hot and bogged out on the warmer
days ( Nova scotia march weather + 5 daytime)
I can remember taking the hood and cowl off
and driving it that way to get more air flow.
If you get enough airflow it should work .
You might even be able to use an electic fan
from a front wheel drive car and mount it behind
the seat back. Rob.
