Lots of discussion on the various Sport and competition camshafts exist, the Sport 310 lift, the R17 and R20 with a 360 lift come to mind but what about the original 1963 camshafts?
Having just rebuilt a very early Mk1 Imp engine, number B41 / 1/ 501572 I find that the camshaft it came with is not as early as the one on another early Imp head I have.
This is cam casting 7010141 and after running the rebuilt engine for a number of hours.
Note the original Solex carb with the auto choke fitting, its under the black cap. Brian Baylis has posted me the two missing copper pipes and from New Zealand, many thanks Brian!
The engine is a static display, at this time I have no car to fit it into.

More casting numbers, what does 2350 mean?
The letters MC, meaning what?
I set this early Mk1 head up with the camshaft the engine came with, only to find that the Mk1 head set up just some weeks before had camshaft number 7010000, was this the very first issue?

very interesting Roy. There is a head for sale on Ebay just now and the cam in it has that number (7010141).
ReplyDeleteI looked at my March '71 Parts List (photocopied for me by Brian Baylis in 1989!) and it only shows 3 camshaft numbers:
'7100000 s/d by 7100411 CAMSHAFT except Sport and Stiletto'
'7100423 CAMSHAFT Sport and Stiletto'
So it's a bit confusing. Looks like the parts list should have read '7010000 s/d 7010141' or '7010000 s/d by 7010141 s/d by 7100000 s/d by 7100411'
