'68 318 to carbed Magnum 5.2: Check my checklist
The rebuild kit for the power steering pump arrived today, so I took it upon myself to discover the idiosyncrasies between the two pumps:
The impeller assembly on the left, with the thick vanes, is from the '67/8 pump. On the right is the '89 pump, with thin vanes, and an extra slot across the circumference (presumably to suck in PS fluid via capillary action to assist lubricating the vanes?):
From what I've read, mixing and matching these to the bodies isn't advisable, as they wear to everything around them. Whether this is true or not, I cannot say. I'll take it as a given and not try to mess too much with it.
That said, the '89 shaft is an uncomfortably tight fit in the older pump, so the shaft bushing will have to be swapped in the hydraulic press tomorrow. Not fun...
EDIT: I completely forgot to post these photos two weeks ago. This is what was in the oil pan of the '68 318. Molasses oil:
Not a pretty sight. I'm glad I chose to replace the engine and not just throw a pair of heads on the original motor.
