1966 6yl Power Steering conversion help

[retrax]

Hey guys, my 66 250 has the double groove water pump pulley but only has one groove on the crank pulley. Does anyone make a pulley that mounts on front of the crank balancer that adds a second groove or do I need to look into pulling the single groove balancer that is on it and replacing it with a double groove balancer?

It would be easier to swap out for a double groove pulley. I have both kind. I prefer the double groove that’s all in one.

I had a 250 installed in an M715 5/4 Jeep & needed what you need. I found a late 80s Chevy in my neighbors junk yard & got the HEI & all the pulleys offa it. But beware the pulleys AND WATER PUMP flange stuck forward about a 1/4" farther than the old single pulleys which were early 70s vintage. The engine I removed the double pulleys from was the integral manifold variety. I had to install the later water pump to make all of it line up. I don't know if ALL double pulleys are this way or not just measure careful while you search!

That bracket is nice.
