I agree white the ones that said stick with what you have in there as changing engine sizes will cause more headaches than it is worth. 360 hours in nothing one one of these engines unless it has been run very hard all it's life.

I thought those camshaft issues were resolved back in the 80's. I made quite a few bucks doing cam, lifters and timing chains back then....right in my driveway, nights and weekends. The good old days....

ya, you are correct. but I believe all those engineers have retired and the new ones never got the memo. 07 through 2010 or so had the same issues as they had back in the 80's. I can't tell you how many of these cam shafts I have replaced. it's funny we would see a new model car come in and we would see something they tried twenty years ago and did not work, just to see it not work again. We would just shake our head when we saw these cars come in with the same problems we have seen in the past.
