Reply to "500 BHP 351 Cleveland"

Mark,

correct me if I misunderstand. Your position is that the wrist pin intersecting the oil ring, especially as little as it does in a 351C 4.00" stroker with 6.00" rod, is not the source of oil burning in these motors, its the cylinder prep that results in the oil consumption?

If so, is it then possible to build a 4.00" stroker, 6.00" rod, 9.2" deck motor, that didn't consume any more than a quart of oil every 5000 miles?

That would be very good news. I have been told by other engine builders that the wrist pin intersecting the oil ring was the source of oil burning, and this is what I've passed along to the members of this forum. I never understood why it would cause oil burning, it didn't make sense to me, but I accepted it as a empirically determined fact.

To get the rings to seal so there is no blow by, I'm impressed. Now I understand why your runt is as powerful as it is. I was taught as a young man that ring seal is everything in terms of the potential of a motor.
