Jerry,
Yes, I am aware of the cause - the fan IS too low. I only recently realized that this was a problem with installing a 235 in place of a 216 (and no, I never noticed until it was pointed out to me). At this point in time, I am at least satisfied it is not an engine heat problem, which was my biggest concern. So, at this point I am left with treating the symptoms, but not the cause (have I seen Rocky Horror Picture Show too many times?). When the money is available, I will spend $500 for a re-core of the old radiator plus the cost of raising my fan location (which can't be done with the current after market radiator).
