Inliners International Forums General Discussion Engines Cast 307 Pistons in 250 L6 swap

CNC-Dude -- The .020 was just an idea as I run a .042 crushed in the 194 motor currently in the dragster. All valve clearances will be run to make sure I have the clearence with the FT pistons, -0- deck and a 560 lift cam.

Do you have a feeling on the CR loss with the big chamfer on the current 307 cast pistons?
