I like them, Picked up a 2012 5.7 for core price awhile back. If I didn't have a fresh 400 short block and new heads sitting in the shop already. Yep, I'd of made the switch. Plenty of fast gen 3's, Steff, six pack gut, Dustin, Granted, I'm not looking to set the world on fire hp wise, but after splitting a cylinder wall in the wife's car. I'm down to my last good stock block. At least I'm hoping it's good, waiting on sonic numbers and mag. So I might be switching sooner than later!
