Re: 327 Engine Operating Temp Range

A question on the heavy duty post 51 327 engine fans mounting to the pre 51 327 engine would be hub size and center hole bore on the fans. They did offer a heavy duty fan for the earlier engines so they are available but no idea what if anything might have changed in the later fan mounting.

While the blocks are essentially the same the pump castings are different and I don't know if the 327 hub sizes changed with the pumps and years. Do know the 356 fan uses a much larger hub and bore so the later heavy duty fans would not fit on those engines.

With the pre 51 radiators being taller and narrower than the later radiators fan diameter may have changed after 51 and there could also be clearance issues.
