Chopper,

I've gone ahead and ordered a Griffin radiator after several conversations them. After all was said and done, they said the 28" x 19" radiator with 1.25" tubes would work (hope they aren't wrong after reading your post). They based this on my motor (FE390 - 400-425 hp as a guess) and me using the Spal fan setup with about 85% core coverage.

Another thing they suggested was to reduce the water pump pulley size to about 70% of the crank pulley size to get more flow. Right now I am running an Edelbrock water pump so before I decide whether or not to make this 'ratio' change, I need to go through the numbers and figure out my current flow.

Right now, I'm using a 1" tube Griffin with a mediocre fan and no shrouding. With my current setup, the temp is really only a problem on hot days in traffic and/or idling too long. I would expect this new setup to perform much better. In the end, if I have to, I will shroud to 100%.

Thanks for the info, looks like I'll be pretty close.

Gene
