This is a 68 302 water pump housing. It has been stripped of the internals.
You may notice that the water outlet is on the passenger side. That was changed to the drivers side in 1969 and later, but other then that it is the same pump.
You can see the height of the bearing support and as I have the guts out and can measure where the bearing and seal sit internally, it is very clear that the nose can be machined down at least 1-3/4" if not a maximum of 1-7/8".
The bearing, seal, impeller locations will all remain in the same location. The "weep" hole remains untouched.
What would need to be shortened also is the output side of the shaft, and a new flat pulley made.
This indicates to me that shortening the snout on the pump is clearly doable and therefore, having a two level "flat cover" v. the four level as in my pictures is very feasible.
I don't have a mill to machine a housing down and I don't have a seperate 289-302-351w water pump to see how difficult it would be just to use an existing shorten version of them to the Cleveland?
It would seem though that it would be simplest just to cut down a Cleveland version?
