my shop guy said i have a 340 bore on my 360 block said it had a 4.04 must be 40 over ? how do i fine compession? i only see numbers on the pistons. als
you have a .040 over 360...which is 4.040...
compression is based on the alot of things....head gaskets...head cc...compression height on the pistons...
need alot more info to figure out compression...
what pistons do you have....what heads....what head gaskets...???
