thanks
I'm concerned today to compare the two models because I would like to upgrade my 2.0 E with S pistons and I own a 2.0 S MFI pump 69 . Then If I use 2.0S piston '68 carbu is it quiet the same result (9.8 instead 9.9 CR ? )
If I use a S carbu pistons , is it possible to put heads of 69 S due to larger valve ?
I know it s a bit complicated but ....
