So what was the old cam? and how did you like it and what changes do you want to make
what's your compression?
I will have to check out the timing chain tensionor working on roller chain issue- now where are my receipts...
Don't know what the old cam was as the numbers are very hard to read, it definitely is not the stock cam, for what it was it ran ok. Valve springs had shims under them so I assume who ever put the cam and springs in had to shim them to get back to the right height. Compression was 152.2 average.
