Title: A7 from A 10 Cases
Post by: Humble Pie on 19.10. 2010 14:14
ok then,,having found out I can use these cases. My first questions are

The cases are 1959 CA10R HHC 83XX  ie 59SR. The cylinder studs are the short ones ( thats a plus in this case )


Now is it safe to assume the cam is a 357 ? ( its still in the cases )

Also do I need to change bushing etc ,,for using A7 internals over the A10 ?


My end result for the motor is one that can cruise at 60 here and there without wanting to explode all over the road.

All bushings and bearings are the same. The cam # is stamped on the end in the drive side case.
The A7 being a little shorter makes the rocker box job a bit easier.
I luv my A7, will sit on 60MPH all day.
Cheers
