crane cam 168731 ???
 

Hello All,

I have a stock zz502 camshaft with new heads ,just ran the rebuilt engine and noticed a bent exhaust valve . I was told by the head manufacture that it is impossible for water to come in with a stuck exhaust valve which I disagree. I believe they are just tring to past the buck. I sure that this bent exhaust valve was caused during shipping and did not hit anythine internal. Their is no marks on the piston ,valve or seat. But anyways I would like to change the camshaft to a crane 168731 while this motor is still apart. any suggestions on this camshaft. Thanks. Alec:party-smiley-004:

What exhaust do you have now ?

I've got a used one with springs if your interested. Pm me your email or # and I'll tell you about it.

I have two 168731 cams for sale also if someone wants to do a twin setup. These cams will work with the stock lifters and dog bones, just need to change springs and buy correct length pushrods.
