O.K., the article was abreviated in YBM & may have been out of context. Thanks

There was an article many years ago about the 1964 (?) Ford Indy engines reprinted in Y-Block Magazine. I don't recall anything about the crankshafts being mentioned, but those SBF based engines, apparently used some of the upper valve gear from Y-Blocks, because the factory SBF upper ends were considered to not be durable enough for a 500 mile race. Apparently, some of the mods were put together with Isky involved..

I gust came across this old post ,
I remember  Reading About  the  Shelby team using a 292 truck crank in both there AC Cobra and there GT40 cars,
These engines worked well but the extra stroke added stress to the 289 block causing Cracks in the main webbing.
They stated the engines were  ok for short races but they wouldn't last a 24 hour race like Lemans!
 The cranks   Shelby used were destroked to 3.25 stroke!    The information was quite limited  because
Shelby didn't want to many to know what  they were doing to make the cars competitive!

Well, I found the article in Oct 1964 Hot Rod, and it wasn't what any of us thought.  Ak Miller was building a stroker 289, "just because".  Hot Rod reported on it, and Isky tested it on his dyno.  Crankshaft Company made the stroker by machining the rear flange and front snout to small block configuration, grinding the mains to size, and grinding the throws to 2" to fit the CSC's special rods with Olds 215 rod bearings.  Offset grinding was available to allow up to 352 cubic inches.  Apparently it worked well enough that CSC decided to market them.  It would be much more difficult to go the other way, putting a 351 crank in a Y.

Ted, if my old brain is working right this morning, I think I remember the late Richard Gaston talking about the early 60's Indy engines in one of his articles. But since the rules only allowed 255 cubes at the time they must have been used to destroke a 260 block and since Ford was deeply involved in this project there may have been extra block machining performed.
