Stud—long (3 1/16 in. O.A.)

A long cylinder holding-down stud (3 1/16 in. overall), used in the crankcase-to-cylinder assembly.

PN · 70-8079

70-8079 is a long stud, 3 1/16 in. overall length, listed in the Cylinder and Crankshaft section of the parts book. Studs like this hold the cylinder block down to the crankcase, giving the barrel a solid, even clamping point once the head and holding-down nuts go on.

Our catalog record shows it under the number 70-8079, with E8079 as the older-style alias for the same physical stud. The listing appears in a single catalog entry tied to 1968, so we don't have a broader fitment history on this one beyond that.

If you're replacing studs on a bottom end rebuild, it's worth checking the length and thread engagement against what's actually in the case before you order, since studs in this area aren't all interchangeable across years and engine sizes. Give us a call if you want us to confirm fitment before it ships.
