    Looking for a fan spacer to help the vacuum canister on my HEI clear the fan on my 225 V6. Thanks!

    If you get a AC Delco D1366C vacuum advance for a 1975 Buick Skylark 3.8L, the hose port is off to the side for more clearance.

    Works on my Jeep with no fan spacer:

    Thanks fireball, you seem to have a lot more clearance than I do, even though my hose port is already off to the side. I don’t know where the vacuum port will end up, but if I have to turn it any further counter clockwise it will hit the fan..

    You can install that HEI so that the vacuum can is closer (under) the radiator hose so as to be away from the fan. (it's proper location)

    Interesting. My V6 is a 77 231 odd-fire. It must have a longer water pump than a 225. A spacer seems like a good idea.

    I just rotated and did a test-fit. I am able to tuck the canister closer to the radiator hose, but I don't get much adjustment on the distributor body if i need to adjust the timing pretty far. We'll see how it plays out.

    Sent you a private message.

    It looks like you have inches of clearance with your set up. Could be the water pump, or the offset on that 3-step pulley. who knows!

    This thread confirms it. 231s have longer water pumps: Buick V6 water pumps lengths

    Now I need to double check my fan to radiator spacing when I put the new radiator in. I might need to source a 225 water pump/pulleys and maybe a spacer myself. Yay for scope creep.
