This may clear up the three core. My car is a 400 4 speed car. But when i ran the PHS it came back as a 350 2 barrel auto car. So I see why it had the three core. I should of bought a 4 core when I purchased the three from Ames. I just didn't know at that time.

And I thought I was ok it's just the highest I have seen it and wanted to check. Wonderful!! Thanks

P.s. I have the Flex fan (stock) that doesn't have a cluch. Is this ok with AC? And anyone else have a [censored] of a time getting the compressor belt tight enough? It's hard to find a place to pry against to get the tention.
