I'm starting the restoration of my 1970 CH. Years ago I stroked the motor and installed later-model cylinders and heads which I must now change back. I know that the heads were changed in 1970. I believe the cylinders were also changed in 1970 as well, but I'm really not sure what changed on the 1970 cylinders. I do know that the cylinders retained the 3.0" bore and earlier head bolt pattern.
What I need to know is whether or not the external casting numbers were changed on the 1970 cylinders. I have 1957-1969 cylinders that I can use, but not if the casting numbers or actual casting features differ. Please advise.
Thanks and HAPPY NEW YEAR!
