I'm in LA right now but will be in Atl soon. I'll post a few pictures on here when I get started as of right now I'm basically gathering all the parts and hoping for two weeks of being home so I can start putting her together. The dry sump I may have close to figured out I hint need to find a spot to mount the 2 gallon oil tank. it's 6" in diameter by 17" tall so a little tricky.

Look at the JW Bellhousing for the th350/400. It's considerably smaller than the stock piece and SFI approved. I'm not sure how well mine would have fit with the stock bellhousing but has plenty of room with the JW.

Also, unless ATI is doing it differently than when I bought mine, you will get a huge sheet of aluminum when you buy the adapter and will have to cut it out yourself which is a pita!

When I did mine, noone could tell me what starter would work with it so I had to do some digging at a junkyard. I use a direct drive (non gear reduction) starter from a 97 Nissan pickup with the ka24e. I forgot why now, but a gear reduction starter would not work. Had to be direct drive with no "snout" on the face of it.

Nope they are still doing it the same way they told me I gotta cut. Thanks for the info on the starter that way I can start looking. I didn't buy the TH400 from them I got a coan racing one pretty built for a steal so I bought it. It has the standard BBC housing with a csr carbon composite shield on it so we'll see about fitment.
