Title: Differences in the mounting points of alt., power steering and fan.
Post by: Tom Gahman on February 19, 2020, 09:05:07 PM

Hi everyone,
I'm aware of the early blocks with out the forward facing hole for the alt,
and I recently found a second type of water pump hub. Are there other differences? For the power steering ? The two dampers I have, put the belt in the same spot. Would this be true across the board?
I'm interested in mounting point variables for performance applications, not casting numbers for particular years or models.
Thanks.
Tom

Not sure if this is the sort of info you are looking for or not, but I am aware of at least 3 different FE water pump castings. the real early pumps, (58 & 59) have a much larger thermosat bypass tube (3/4" vs 5/8" for later applications) with the temp sender threaded into the bypass tube. The water pumps used with generators were different than alternator equipped cars. In addition to the threaded boss in the block for the alternator thru bolt, the gen water pumps have a dowel pin, used to position the 1 piece generator bracket. The alternator water pumps replace the dowel pin with a threaded bolt hole, as well as having the bolt boss shorter.

Make sure your timing cover and balancer combination agree where #1 TDC is. The crank pulley to block face spacing never changed. Roy covered to hard part of your puzzle.

Thanks Chris, hadn't thought about the timing marks,though I always verify at assembly.
Thanks again.
