Was trying to figure out today why the 3/8" pulley water pump costs more (and much more in some instances) than the 5/8". It's because the 3/8" was on so many fewer engines for fewer production years.
So a debate (in my mind) lingers on. Go with the 216, 5/8", balancer, 5/8" water pump and change the pulley on any altnerator I'll ever need and use, or go 3/8" with everything but spend more on water pumps...
