Trans coolers, fans and consistency.

Also something I learned last year. I ran a ac 8 impeller water pump with the stock 68 ac waterpump pulley. Which I believe is smaller in diameter. I had noticed the year before that there was some cavitation pits in the timing cover. Not many but some. Pulled it apart a year later and there were pits everywhere! Its see’s 6400 rpm max. I was in there to cut off four of the impeller arms anyway so I installed a anticavitation plate. Higher rpm and the 8 blade impeller really needs an anticavitation plate.
