Garry is there anything in your memory about putting a Lockwood Racing Chief on a Speedibee tower and lower unit? I do have a reason for asking. A racer in Michigan passed away a few years ago and left some stuff out of his garage to a member in the club I know. In going through the stuff on I found a strange tower and clamp bracket assembly that went to a lower unit that used the 3 blot system to bolt it on. I sent the tower to Jim Ross and he found that the only lower unit that would bolt up was SpeediBee. He also found that the only crankcase that would bolt up was Lockwood Chief.
