Dorman 594-117 harmonic balancer
This is a stock replacement part for many GM engines ....so would it be reasonable to assume that it would hold together for an occasional 5,000 rpm blast? .....sorry, also which is a better part for just cruising around and again an occasional full throttle run. A cast iron or aluminum water pump .......... thanks

On water pumps, rumor has it that aluminum housings can deteriorate and develop leaks if not driven regularly. It's the pull of the belts on the nose. I'd stick with the parts store replacement pumps if the car isn't driven much and you're not looking for the aluminum bling.

Ranger/oddball ...... I bought the Dayco PB1147N Premium, paid $76 shipped....good deal, thanks Ranger. I 'll be using the flow cooler 1776 alum. pump which is the 5.65" unit. It will only have one belt on it driving the water pump and alternator, will use a Spahl elec. puller fan. thanks for the info.........Dave

I would use caution in relying on Dorman's application list. For example, they claim it fits Oldsmobile from 1964-1980. The 1964 330 motors have a unique TDC mark location and will not interchange with balancers of other years (unless you scribe a new timing mark on the balancer for that motor).
