lcrken said:The pictures help a lot, Jeff. I think what you have is a Dunstall MK 3 Street camshaft for an Atlas engine. I could be wrong, but that's what it looks like to me. Dunstall came out with the MK 3 around 1968, or maybe 1969. Ken
Dunstall advertised his "street cams” as suitable for all the Domi engines.
There should be the timing of these in a Dunstall tuning book
You can use a pair of V blocks in conjunction with a timing disc bolted onto the cam with pointer and a clock gauge to find out the lobe timings, out of the engine, it’s relativity simple.
BUT, as someone else has mentioned, don’t be surprised if the timing between the top of the lobes don’t seem to correspond with anywhere near what it should be, -it means you have a bad cam, in which the cam grinder has turned round the cam in his cam grinding machine in order to clean the lobes up-don’t ask me how I know :!: :shock:
