360/410 Stroker Questions

If I may ask, what is your theory or experience on this? At what value would you say side play becomes important?

My only references in this area are the factory books & Larry Shepard's book. He says .017 is max & .020 is start over - oil pressure will be too low & the excessive oil squirted on the cylinder walls will overload the oil rings. It is unclear to me if he is speaking of a street performance engine or a race engine, or if that distinction matters. Thanks.


You can run .150 side clearance and it won’t make a pinch of **** of difference.

This is another one of those long cherished lies that get repeated, even by the book writers and experts.

Rod bearing clearances is what controls oil past the rods, not side clearance. In fact, if I only had .020 I’d be finding more.
