Got word from SHM about cams for the truck, no luck. I was told they just got a lightning and would be working on a cam. SHM did say they had heads the were good for 15 - 20 hp for $1,500 with exchange. Now that's a lot of money for 20 hp not counting the labor to make the change. Talked to a guy that works on these swirl heads and was told to be very careful with them because it was easy to make them worst than they were from the factory.
So I am waiting to learn from you guys. Thanks for all of your help.
