My experience has been fantastic with Tim @ FHO. This is my third build with him, priors were 2, 572. Never a problem, and were really run hard, both NA, sold both in perfect condition according to the buyers who are still running the original builds. My latest arrived a few weeks ago, 572 Procharged, dyno 1574 HP and still has a few hundred HP moe left according to Tim, will be very reliable too. You can never go wrong with him.
