t56 is the best tranny ever made!

(one of the) best PRODUCTION trannys ever made

I'd personally go with the LT1 modding wise.

Lt1's are not that fast, and are complete POS's IMO. I ran with an LT1 on a 0 to 60-70mph sprint in my last 5.0, which had a 5 spd, full exhaust and stock 2:73 gears. His auto LT1 had a cat back and a CAI. When we shut it down, the nose my stang was even with his front tire, basically a tie, and I did not powershift. I was not impressed. True, he had an automatic and I had a 5 spd, but I had 2:73 gears, and was giving up 50 cubic inchs, and lost by less than 1/2 a car length. Not impressed.

Not to mention, LT1's:
Look like ass
Are a B**ch to work on
Have various problems (Not that 5.0's don't have a few quirks, but not nearly as bad as LT1's)
Parts are more expensive
Horrible hump inside car
Handles, feels like a rattle trap POS when driving/riding in one.
Interior ergonomics such ass
...etc...

LS1's share many of the same "Camero turn off's", but are MUCH better cars overall, and are MUCH faster, but obviously cost a lot more $$$.

LT1's arent that impressive, but the LS1's are a lot faster. A simple mod on your mustang and it'll have with LT1's all day long, takes a few more to keep up with the LS's though.

Yeah, LS1's are fast cars! My dad has a '99 LS1 Trans Am. It's quick. The LT's though, a few mods and you should be able to run with it. Just my .02
