I need a new stock or mild performance cam for 330hp
 
I know I am probably the first person to ask for a stock 330hp cam on this site ever lol. I am rebuilding a gen V 330hp motor back to stock, low hour engine that has some rust on the cam so I am not going to trust it being a flat tappet. As I have figured out over the years, most of the black engines have a GM equivalent cam that is usually much cheaper than mercs priceing but I am having a hard time matching it up. If anyone knows of a non merc part number or have a recommendation for a low budget mild cam that will work with stock exhaust, it would be appreciated. Thanks

Depending on how far the engine is assembled I would put a degree wheel on it and see what you have now. That way you have something to compare it to when you are shopping.
