Use a table ban saw to hack off the 340 piston crown .

This thread is all 'BACK TO FRONT'!

Its the 360 pistons that are too tall for the 340 block as I've 'BEEN THERE DONE THAT' myself.
The 340 guy bought cheap used forged 360 pistons for a 340 build.
Had to turn about 30 thou off them to get the compression right...

UTG would have used them as is a run some race gas lol...
