I just received my 464 BBB from TA Performance yesterday and felt it was worth a post here. I was really blown away with what I received. I placed the order late last year and provided Tim and Mike some very lightweight specs on what I wanted, basically a strong streetable motor based on the 455. They showed a very high level of service and professionalism going over every aspect of what I needed, and answering every question I had. I had a chance to see the motor at their shop in the late winter when I was headed west to see my oldest son near LA. They had it mounted in a rigged up engine stand and it sounded very good and healthy. I asked for a custom fit dipstick to be put in, since the motor would be used primarily on the street. Mike took the time to do a great custom fit with the headers that are planned to be used, so I shouldn't have much of a problem doing the install in the car. The quality of completed job is astounding. Everything appears clean, unscratched, even the fasteners. Basically, it looks perfect, even after being run for 30min. on the test stand. I didn't really pay that much attention at that time when I saw it running, but after checking it out thoroughly at home, the care and attention to detail that these guys have is really outstanding. The motor comes fully documented in a booklet that is specific to my engine. Even the picture on the cover is of my motor, not a general shot of some of their prior work. Every aspect of the build is fully documented, including block prep, head work and flow bench testing, camshaft specs (Mike suggested a TA roller vs flat tappet), even the connecting rod specs. The shipping crate itself is a work of art, so to speak. Very well thought out and very well put together. Many, many thanks to you Mike, Tim, Santos, Sherri and the who TA Performance team out there in Scottsdale. A class act all the way. I would not at all hesitate to recommend them for anyone's engine build. I have attached pictures of the motor, documentation and crating below.
