270 Hemi water pump


I have a 270 Hemi which I ordered your small block Chevy water pump adapter for. There are two different small block Chevy water pumps a short and a long. To use all my original pulleys and retain same distance for belts aligning and all, which pump do I use??

On my 331 Chr the long BBC lined up nicely, don't know about your Dodge.

This isn't exactly on the point of your question but maybe it will be helpful in getting your accessory pulley's aligned.

Take a three foot length of straight 3/8" brake tubing and use a bending tool to make a roughly 90 degree with about 5" on one leg and leaving other leg full length. The 90 degree end will fit tightly into the crank or water pump pulley v-groove at two points. The long end becomes a very accurate pointer that will tell you the exact point where the mating accessory pulleys need to live. It works no matter what orientation your engine stand happens to be in.

It won't make the brackets for you but it will ensure that your pulleys are aligned when you're doing the shimming/bracket work. Note: this works for v-groove pulley's only. I hope it helps.

It may be that none of it lines up and you will need spacers. A plumb bob comes in handy to hang from the top pulley to align the bottom one. I used a Big block chevy pump and nothing aligned. I made my own two belt water pump pulley and a large spacer for under the lower pulley . It was one of the hardest things I ever machined. Took some thought. my lower pullet was from a different Mopar application that fit.
