I think if you have really tall gears from a later 2nd Gen TA, they will be either 2.41, 2.56, 2.73...or even 3.08's, so I would opt for the 2800-style cam myself. If you had 3.23's, or lower, then the 2801 (check piston to valve clearance) would be my choice. The slightly higher stall converter in your TH400 will help some, but if it's pretty tight you'll want to create as much low-end torque for the 350 as possible. My '69 4-dr Custom S 350HO has the TH400 and the standard 3.55 gears, weighs 4000 lbs. and seems really gutsy everywhere. It has the 067 cam and sounds like a 400 with the 068 at idle. The 350HO will move your TA out nicely, won't set the world on fire, but you're not street racing the thing. It is a great looking clone, btw.
