Dave,
Thanks. The response was from an old post on the forum right after Griffin
announced the radiator / fan combination. I took a look at my '67 and
thought there's no way that'll fit. So I followed up with Benji at Griffin.
The note was to report back what he found: 1 1/2" radiator core, 2 1/2"
fan. No way that'll fit with a motor driven water pump. He said they'd sold
lots of them. No comment so far from anyone who bought one.
My 289 has a recored stock radiator, the shop said it was a "high
efficiency" core, @ 2 1/2" thick. The engine's .030 overbore, Edelbrock
heads, manifold, cam, Holley carb. and a Summit "wide paddle" flex fan and
a Summit 10" pusher fan behind the grille a la TEAE's recommendations. At
an idle speed @ 675 rpm it will overheat in the Florida heat. I installed
the Maverick reduced diameter pump pulley, it seems to help but in summer I
kick the idle up a bit.
