Interesting idea if it works and definitely cheaper than a repro pump. There were two style pumps for that block the main difference being in the later casting which moved the fan and pulley down due to the much lower radiators in 51-4 cars.
Is the water distribution tube intact, clean, and in good shape the entire length? A dirty or damaged distribution tube slowing water down or letting it leak out somewhere instead of squirting on the exhaust valve seats the full length has been found to be the cause in many an overheating engine.

Good point, the block is surprisingly free of rust and scale, the water distribution tube is brass and slid out easily, unlike the Dodge six flatheads I fixed up where the tubes were rusted in & came out in small pieces.

Yer but. Some poor B will end up with your car and have a water pump issue and wonder what the heck is going on. It sounds good but I would recommend that you put a repair kit through your existing pump. It would also be a good idea to convert the 288 to the 327 and bore it out 60 thou. Good luck anyway. I may have some parts if you need same.

Any poor B that buys any of my cars knows they are fully custom built & nothing is original or standard. I'm in Australia . Everyone here knows what a Holden water pump is & I'm sure they will be happier to pay $45 at any corner auto store than import a repro pump. The Packard engine I'm fixing up is going into a '29 Chrysler frame with a custom built speedster body . Its stupid to bore a good STD block out to 60 over to get what , another 5 cubes , yeah thats going to make a difference, not. Now if anyone wants to rebuilt it needs to be sleeved. I prefer 288 over 327 , slower piston speed wins for me.

Yes a lot of people do prefer the high revving 288's over the luggable 327's.

A 327 with OD or a 3.75 ring & pinion would be nice... 327 & OD with a 4.09 in a 120 would be sweet. Most displacement is in the stroke, so I'd limit any boring as far as practical.

How about a 327 with overdrive and a 4.7? That’s what my 1951 has but of course it weighs three tons too.
