"why would the cam need to be changed?"

This has to do with intake/exhaust over-lap or seperation. The issue is reversion and the likihood of an exhaust valve allowing water into a cylinder at low RPM.
Best to use the marine camshaft along with the other marine items!

"The marine cams and heads show up on eBay/Craigslist with some frequency. I had one but gave it away to the guy for free when he showed up. Showing up is half the battle.

"The marine cam for the AQ120B

"The marine cam for the AQ120B, AQ125 and AQ131 is an "A" cam, part number 1376767-7. Make sure you install an A cam when marinizing a car engine if you go with single carb, and either a V or a K cam if you go with dual carbs. Of course, you also need to install marine carbs, distributor, starter, alternator, fuel pump, intake and exhaust manifolds, raw water pump, cooling expansion tank, etc."

"thanks,it looks like there is a car motor in the boat know looks like someone swaped over marine parts.how do i know if the cam is marine cam."
 
"Look at the part number I ind

"Look at the part number I indicated in my previous post, it may be on the cam. Also, there should be an "A" (or a V, or a K, depending on which type of cam they installed) stamped on one of the cam ends."
