Wow, First time I have posted in a long time but, if you want the right information The HAMB is where you come. So with that said could do with a little help identifying the Cam taken out of my friends 350 earlier today. Why do I need to identify it? Good question! Mainly because it has a broken valve spring, that valve has a mushroomed valve stem (and may possibly be bent) and the timing marks are waaaaayyyyy out of sync. The cam itself is undamaged, the lifters are good and the pushrods are straight. So, the need to identify it is to ensure that the correct valve springs are procured and the mystery of the off timing marks can be solved. What are the markings on the cam then Paul? Glad you asked - This is what is cast into the cam EP6 30 D8 C8 C5 CWC There is also Blue and Purple paint on the distributor drive end of the cam and a 2 white spots half way down. On the distributor end there is also an A cast into the shaft. Other than that there are no marking or casting number. I 'think' that it is a Chevy cam rather than an after market item but happy to be proved wrong. So, what does the panel think? P.
