Jim, I baught a motor from them 3 years ago. Dynod, broken in, 660hp 358ci, naturally aspirated. I have broken trannys, axles, hubs, mounts to name a few. These guys are first class. Read thru the posts on this forum and see all of the broken motors. I adjust the valves and change plugs and
oil, thats it so far. RDI is the way to go. scott
