If you are a decent mechanic that isnt too hard of a fix. And would give you a chance to do a good bit of upgrades if you were willing. A cam kit from thunder racing or tsp... Which would come with new springs, new pushrods, cam, and a crank bolt. Pull the heads. IF you had the money you could get them cleaned up with some pnp. While they are out replace all the lifters with the ls7 replacements. With heads out of the truck it will also be far easier to put the aftermarket springs on. Throw in your new cam. Put some arp head bolts on for good measure and done....
To the OP that is a good cam in the 4.8. Id couple it with a 3600 stall. Good bolt on and gears. Set up should be good for 13s.
