Bolt pattern, head to cam tower
 

I will make a fixture for surfacing of cylinder heads (3.0/3.2)...does anyone have a dimensional sketch of the bolt pattern of the studs and guide pins? Please share if you have, thanks:)

Robert

If I am understanding correctly...You want the bolt pattern for the Heads to Cam Housing??

Hopefully I have what you need.

Robert I chopped up a defective cam tower maybe 30 years ago and am still using it.
If I make a new one I will send you the file but for now I am a little busy.

Thanks for your reply...maybe my request was a little unclear, this is what I'm looking for:

Agreed with racing97. Use a junk cam tower to do most of the work for you. All you need is a plate to connect the hunk of cam housing to the lathe.

I have a junk housing if you need one.

edit............ Even creative John at Costa Mesa R&D uses the tried & true hunk 'o housing https://www.youtube.com/watch?v=dncyBPHCKyQ

Thanks Kevin, that's a clever solution to this, will keep that as a plan-B. My plan-A is to use a steel disk I have that suits my Lathe well...will give very high precision I think, just needs to drill the needed holes in it.

You will need some lateral adjustment some years are not concentric to later years centering will be an issue if you make it solid to the lathe.

Important point, thanks. Will try to make a fixture that can be moved around a little in the Lathe to get it centric.
