Cams...How to determine what I have.
I had a 2.7 built with a 2.4 case in 1978...
The engine is out of a car but I can run it. Originally we put Solex cams in the engine but later we changed the cams and I don't remember what we put in there. I cannot find the invoice for the second set of installed cams. And my question is: if I use a dial indicator to measure the lift of the cams and put a degree wheel on the crank to measure the duration...correct so far?...and write the specs down would someone be able to tell me what cams I have? Thanks. |

Yes that will work.
This should help you identify the cam

Tom,
I just came across this...thanks for posting the chart! Are the part #'s stamped on the end of the camshaft opposite of the cam sprockets or would one have to measure the cam lobes to determine what camshaft it is?

In some, but not all cases, the P/N is stamped on the nose of the cam.
The casting P/N is cast into the body of the cam and is usually the same as the first 9 digits ion the part number. This allows you to narrow down the possibilities in an unknown cam. You can also measure the lobes with a hand held caliper to further narrow things down. However, in some cases, it is necessary to put the cams in a cam doctor to know exactly what you have. Here is how I did it... DIY Cam Doctor
