will a th-350 drop right in in place of the 400( crossmember, driveshaft, etc.)? how much faster will a strong 350 run than a 400? how much more hp lost through the 400? thanks, greg

No. You will need a longer driveshaft and a different yoke, unless you have a super rare early TH400 that uses same yoke as TH350.

will a th-350 camaro driveshaft bolt to my 12 bolt yoke?

what about the crossmember?

Cross member will need to move back to back set of holes in the frame. TH400 uses the large M22 style yoke. The almost TH400 that was referenced in the other post is a TH375--not easy to find--built in only a couple of years and I believe BOP trans mostly.

Depending on which TH350 and TH400 you have, you may have to change drive shafts.

There are three basic TH350 transmission lengths. 6", 9" and 12" tail shaft. USUALLY Camaro's hve the 6" tail.

TH400 come in three lengths too 6", 9" and 12" but the case is longer. I have two of the three TH400's for sale as follows: TH400 shorty trans is 29" from top of bell housing to the tail stock. Out of a 70-74 Chevelle. Has B&M shift improver kit in it. $250.00 and TH400 medium length--34 5/8" from the top of the bell to the end of the tail stock. Has stock converter and flywheel with it. $250.00. $400 for both.
