Stock PR's - Largest Cam?
 

What kind of a cam can you run using the stock push rods? My guess is that its limited by the spring you use. Again, Id guess that the limit is the LS6 valve spring? 918's would probably crush the stock pushrods, huh. Id like to keep the stock PR's as protection against mechanical over-revving bending valves. I dont often miss gears and over-rev... but just incase I do.
TIA!
