Another piston option for the 273.

That's right. Forgot about the width, but, then again "while you're in there". Lol. Doing this on a 360 right now. Also doing a 318 with the scat 360 stroke/ 318 main crank. The 1.74 compression distance piston stuck out .037. With the Magnum head gasket, piston to head clearance was a little tight. Guy got scared and milled a few thousand off the top.
