....again on my 77 400 build, when looking for a water pump, I am seeing in some descriptions "long pump". I was not aware there was a long and short pump for the big block. What's up with that?
I have a 1970 Challenger. Built 383. I have cracked 2 long neck water pumps with RPMS up to 7600. If you are not going over 5000 and have A/C, the long neck is ok. If you plan on running hard, I recommend the short thick shaft water pump.
