I have in my collection of t parts 2 different size sure mike cranks one appears to weight just bit more than a standard crank. The larger one has bigger counterbalances and more meat in the webs. The large one has casting number of R 2377. Any information on these would be greatly appreciated.
I have seen a large version of the Sure Mike crank that was in a dirt track race car that Bill Barth restored for Speedway Motors. Large counterbalance and very thick webs, The mains and rods were larger than a T Model crank but I don't remember the size. There are ads for their large crank.
Mike, thanks I will get my mic out and see what the mains and rods measure
Hi Ralph. I have what must be an earlier version of the Sure Mike crankshaft. The casting # is F8 H. It does have pretty large counter balancers. I'm using a cheap $10 Harbor Freight micrometer, and both mains and rods measure out at 1.25".
Hi John, do you have it in your car?
I've got one in my 26. It's in winter storage at the moment and I really don't want to pull the pan but I will say it's my smoothest running T.
Hi Ralph. I am using the Sure Mike in my car. It is out now due to some other engine work being done. I've been running it for the past 9 years, and my father-in-law ran it for almost 30 years. It is a very smooth running engine with that counter balanced crank. Just had it magnafluxed to make sure it is OK. It passed.
The sure mike crank that was in my tour car,was found by my dad in a junk yard near Saginaw Michigan back in the early 50's. He then had a local trade school rebuild the motor and install this crank. My hope is that I can install this other sure mike which is beefier
Ralph, any idea what the name of the junkyard was? That's my old stomping grounds.
No I do not Ed, my Dad has past so all of these secret model t junk yards are gone with him. Ed did you know a William Dreist, he restored cords and dusenburg and lives in the Saginaw area.
Cool to know there was a thicker and better version of the Sure Mike crank made
They must be rare, though? Never seen them mentioned before - and there's been lots of threads over the years about Sure Mike / "Sure break" cranks
Pictures would be great, if possible?

Roger I will attempt to upload. If it does not if you send me your email I will send them to you.
I only found "sure mike" and what looks like a small "cf" on mine. Which webs are thicker? Here are pictures.
Ralph, yes I know Bill. I spoke with him at the 2017 Greenfield Village Old Car Festival. He was there with his wife Liz, serving as a judge. We used to meet for live music at a bar two blocks from the Sure-Mike building, in the 1980's.
I think the webs are smaller on mine.
