Thanks for all the replies. That's a good idea Kip - too bad to hear the chevy won't fit because my friend has an extra 283 just waiting to be rebuilt.

Anyway, if possible I would like to stick to the original engine but we'll have to see.
I'm currently talking to a guy about buying his 280sl which has a pretty rough engine with average paint and interior.
My thinking is that rebuilding this engine will be a lot cheaper because its a single cam instead of dohc like the v-8's. Unfortunately it's kind of a small engine.

In terms of an engine rebuild, is it ever possible to have cams reground/balanced while installing a new valve train or is it always recommended that they be replaced with new?

Thanks again
