Do the cast scat crankshfts come with the small and big pilot holes

My convertor has the big 1.848 pilot hole .I have two 460 cranks one had the smaller size and I had it bored out to fit my convertor .My other 460 happened to have both the big and the small.No machine work needed there.Like the title says on scats stroker crankshafts do they have both big and small? I have been thinking about a pump gas engine for my drag car 502 or 532 .Doug

My 4.15 stroke 9000 series cast Scat crank came with both. 1.85 and 1.375.

Thanks for that info .I wish for had done that with all their cranks .And it is commendable of scat to do so

Last week I emailed Scat on the subject, because of this thread.


Maybe they'll answer someday.....

Good Morning Mark,

Sorry for the late reply, I was out of the office last week!

Our 460 cranks have both the 1.375” and 1.850” pilot sizes in the rear.

It is a stepped hole, the 1st step is 1.375” and the 2nd step is 1.850”

Thanks!

When Ford 429/460 engines had just the 1.845" pilot diameter starting on the 1968 model year, that's all there was on the rear flange. But when they revised to the newer 1.375" diameter, the rear crankshaft flanges thereafter were machined with both diameters (1.845" & 1.375").

P.S. - Little known fact: some of the very earliest of the cranks also had a 1.25" pilot for when the 460s initially replaced the 462 MEL at the very end of the 1967 Lincoln Continental production run since 1.25" is the converter pilot diameter of the 462 MEL trans.

You know I love these old fords and mercurys .But sometimes I wonder why ford couldn't have kept things the same .I had this same issue come up when I was in my early 20s I had bought a used convertor from a guy .Well not only was the convertor pilot wrong .The convertor was fried .I had it rebuilt and the correct front plate installed .Good information and really good to know scat has both sizes .My convertor has the big pilot and I am thinking of building a pump gas stroker for my comet drag car .This weekend I am going to Cottonwood ala. They have a pretty cool nostalgia race and I just hope the weather will be as cool as the old cars .Doug

Ford could be worse.

Imagine if they had a small block called and called it an "LT1"...and it was forty different engines.
