Yeh...thanks guys for all the ....help..... - back to the question however.....

Re ignition system - my reading of the specs is that "Coil and Distributor" system is specified using Bosch or Marelli. What is to stop the points being substituted with an electronic spark system, hidden under the distributor, for that historic "look"?

Wouldn't this still meet the specs?

you are not allowed to to replace points!
you can try but that is easy to spot and will not pass scrutiny!

The points have to trigger the ignition.

There are some systems out there which help give the points a healthier and more reliable spark (that is maintain the correct gap) than a totally standard system.

As long as the points are in there doing the job they were designed for I don't believe there is an issue.

Not that I would know, of course...  :D

How hard is it to read the manual which is quite cleat on the subject :  ::)  ???

CAMS manual says this on the subject:
Electrical equipment: All electrical equipment must be unmodified from the original specifications, and fully
operative.
- The dynamo/generator may not be replaced by an alternator.
- Electronic ignition devices are not permitted, unless included in the original specification.
- Electronic revolution limiters are permitted.

further to that in :
5th Category - Historic Cars
3. Vehicle Eligibility
3.6 Equipment Standards and Guidelines
3.6.7 5th CATEGORY EQUIPMENT CHART

it specifically lists what is allowed and what is not. Breaker-less and transistorised ignition is specifically prohibited.

it should not be that hard, particularly with the manual available for download !

New Avatar Glenn....car is looking good.

Yup, as far as I can work out, points it is.....whichever way you look at it.

And Paul I was thinking of your 'points' while reading this earlier  ;)

The only interpretation is the one used by the rule makers - that is that 48's are fine - the intent is to make you use the same "type" of carby ie "sidedraft twin throat etc" but allow the throat (and manifold) size to be free.  To be clear - 48's (any bore size for that matter) ARE allowed.

Electronic ignition is NOT allowed.

I'm still looking for a new car - as soon as i can find one I'll be building again!!

Can you share with us where we can find these more reliable points systems. Much appreciated

Everything on my Alfetta GT came from Pace Engineering, but this was several years ago. I suggest that you give Vin a call... :)
