340 Piston Selection

That recess is assbackwards,its a solution offered to people who already have those tall pistons in an asembled shortblock,its pretty much an extension of the cylinderbore.

Im out of this now,i have given my opinion on this and hope 1Badcolt will find a good solution to his build,i bet it will run great once done nomather what solution is chosen.:)

I know what it's for. So you'd tell someone to mill .060 or more off a head and waster a casting rather than fix it right by d caking the block? That's just stupid. I say it over and over and over since 1980, if you are running a 340 and the heads are the open chamber type the piston MUST be out of the bore to get the compression up.

If your engine builder doesn't understand that, kick him to the curb.
