Hi Glen,
Being in this area, I understand the problems. I'm running a Cross flow
radiator with a plastic 8 or 10 bladed fan. BTW have you checked your
plastic fan? There are two types, one for the late 1275's and the other
for the 1500's. The later runs the other direction and won't work on a
1275.
We have these problems on the MGA's also. Our fix is to recore the
radiator with the high baffle, 3 core, high efficiency core. They have
more baffles and slow down the air flow for a better heat transfer. If
you have to go and buy a cross flow, be careful as the 1500's again use
a larger radiator and will not fit under the bonnet. I think Larry
Miller couldn't get even the 1275 crossflow to fit under his fiberglass
bonnet. So beware. Mine I have a metal bonnet, and still had to bend
the corners in a little on the radiator.
Good luck.
Rick
BTW with my built up engine I run about 195 on hot days over 100
degrees.
