Hey fellas,
My motor came apart quite easily. I flew it up to Poplar Bluff, MO yesterday and handed it over to the machinist. He's already bored the first three cylinders to 15 thousandths over standard. While boring the fourth cylinder, he discovered a gouge. In order to get the gouge out, he bored that cylinder to 30 thousandths over standard. He said he'll put in whatever pistons I tell him.
My gut says all four cylinders should have the same bore, which means boring the first three out to 30 thousandths over standard. However, the machinist has said he's bored cylinders differently in the same engine before with no ill effect. What are your guys' thoughts? Should I run it with a different bore in number three, or have him bore the entire motor to 30 thousandths over?
Also, he said he's not fond of Wiseco pistons, as they tend to expand more when heated. He mentioned the Pro Pistons and seemed to like them. What pistons do you guys like?
As always, thanks for all the help. Couldn't do it without you guys.
