Guys,
Some of you might have seen from a previous post that I did a tran-brake launch with a converter that wasn't rated for a tran-brake. Nice show for the neighbors that were around, but frustrating for me. Now I'm faced with buying a better converter and having my PG gone through to ensure everything is still okay.

My question: Since I'm making this pure drag car ('68 Nova, 468/blower, around 600 HP) into a street/strip ride for my family, I'm being told that a TH400 would be a better choice since it would give me an additional gear and might even run cooler.

I'm finding a lot of 400's with brakes (still my choice to have one), that can run full manual, have JW bells, better pans, etc. It sounds like the time to make the switch but I'm wondering what else I might be getting into. Shifter, drive shaft work, crossmember, etc. Can anyone give me the pros/cons you've went through in the past so I don't have to go back to the school of hard knocks (again). I'm a manual-shift kind of guy but for a number of reasons I would like to keep this one an automatic, so I'm learning the slushbox lessons on-the-fly.

Thanks in advance for your input...

Hobo
