The question was answered....several times for the 54 engine. Nothing extra needed but the 54 pump.
Was curious AZR....for the 55-62 235 block.....does the "short shaft" relocate the pump so that an aftermarket fan will clear the harmonic balancer and center it on the radiator? Secondly, if I should have a waterpump failure, would I have to sit beside the road until UPS delivered a new "custom" pump from AZ?
I've got a pricey new short-shaft pump collecting dust in the shop and after finding it didn't address all the above questions. I went with the adaptor plate and the 216/235 pump. In the 18 months of daily driving my engine temp has rarely exceeded 180 (even with the A/C), my 6 blade fan is centered on the radiator and clears all pulley's and NAPA can hand me a replacement pump over the counter.
I can appreciate your zeal in extolling the product, but also suggest you realize that there is usually more than one solution to a problem. On this site we share information based on actual performance and not so much on supposition. If you're running a "short shaft" pump on your 55-62 engine and you're happy with it that's great!
