the nuetral balance will have to be the way to go. i don't know which trans im upgrading to other than it being manual. i would like aluminum to be the material of choice, but i wouldn't know which tooth fiting to get? i want to say 153 to cut down on rotating and overall mass, im also guessing that its smaller so it'll fit in more common bellhousings.
why does the t-5 HAVE to have 168? dont i just really have to pay attention to weather it's 10 1/2 or 12 inch flywheel?
is there a way to get my 5-speed from my 88v6 to mate my 400sb? is there a certain bellhouseing that they make for the generation gaps?

a bellhousing off of a 60* engine will not fit a 90* engine, unless you can find some sort of adapter plate as the bolt pattern is a bit different on them.

A 168-tooth flywheel WILL NOT FIT inside a T-5 bell housing. You MUST use a 153-tooth one.
If you build a neutral-balance 400 (which will require using non-stock rods) or you use the little weight plate to"unbalance" a neutral flywheel, all you need is the flywheel for a 83-85 Camaro/Firebird with a V8. You will find that there are 2; a heavy one that went with the LG4 low-performance cars, and a light one that went on the L69 cars. I'd recommend the light one. Seems like the difference is about 16 or 18 lbs vs about 28 lbs. If you want, you can also take this flywheel to a balanace shop, and just get them to re-balance it to the stock 400 spec. UNDER NO CIRCUMSTANCES should you have anybody "balance" the engine and the flywheel together; I would suggest that they NEVER EVER be present at the same machine shop at the same time, lest you "accidentally" get screwed by some well-meaning idiot. Have each part balanced TO THE STOCK SPEC, all by itself, and NOT as part of a "custom" assembly.
Forget the 6-cylinder crap. Go find V8 stuff. We're talking a 400 here. V8 T-5s are weak enough, there's no sense in spending extra money and doing extra work, to graunch a weaker transmission into your setup that doesn't belong there in the first place, just so you can come back and replace it soon anyway with the right thing. Do it as right as you can the first time, and you won't have to re-visit it near as soon.
It has nothing to do with "generations". It's 6-cylinder grocery-cart stuff, vs V8 "performance" stuff.
