[Healeys] Camshaft differences

[Andy Thorp]

Hi Chris,

Thanks for your replies. Looking at your pic and taking a bit of a wild guess, that is a late-ish 3000 or sedan cam at the top, reprofiled Mk2 second, 3rd and 4th 100/6 or possibly Mk1 3000 and the bottom one looks like one of the very early sedan/BN4 engines with 13 teeth on the oil pump gear.

The pic I posted was of the oil pump gear, obviously the distributor drive doesn't change.

Andy.

 Hey Andy
 You mean 12 teeth on the distributor drive
 gear?
 They all have that. 
 Show me the oil pump drive gears. 
 ;-)
 I've shown you mine.
 Now show me yours!
 ;-) lol. 
 Chris.
 P.S. If the 2 gears (oil
 pump and distributor) are the same number of teeth, same
 diameter, then in my book, that's the early type. 
 Pick the early cam out of my lineup....
