I want to buy, though. Please keep talking. I'm trying to get 50 post before I leave work so I can buy my motor. HELP!

Then I would think PMing an administrator would be a better tactic, direct contact would probably go a ways towards convincing them you are not a spammer where spamming your own post just proves you are the spammer that rule is there to block.

Far as the engine size question and fitment. The gen 3 motors can be compared to the gen 1 motors, a 283/305/350/400 all look and fit the same as eachother, same goes for 4.8l/5.3l/5.7l/6.0l/6.2l. None will be any easier or harder to fit than the others.

Far as the bellhousing sure a gen 1 tranny will bolt to a gen 3 block, just leave out one bolt at the top. That does NOT mean you can make the clutch and input shaft work out easily. I thought the T5 was the one so torque limited they only sold a manual tranny Camaro with a 305 for a few years? Probably not the right choice to bolt behind a motor capable of what the gen 3s can easily generate.
Headers and a tune on an LQ4 and it will make 100tq more than the WC T5 was ever rated for and that is without so much as a cam.

I personally went with a 6.0. The torque is way better than the ls1 that was in my car. I have torque down low where my ls1 didn't. My car with the ls1 ran 13.17 @ 107 with full bolt ons. After I spun a Bering I swamped to the lq4 with same bolt ons and ran 12.72 @ 110.98 on street tires. I am far happier with my 6.0 than I ever was with my ls1

As far as a t5. You probly can do it. Idk what it would take but it can live if you are nice to it. My old Turbo 5.0 fox was making over 500tq to the tire and it lived with no problems. Just don't shift it real hard and it will be fine.eventually though there is a point where the case will distort from torque then it definitely will brake

No but 99-2000 have a longer crank so a m6 wont work. If your running a a4 may not be a issue but Idk. The only other thing is you have to drill and tap the block for the alternator bracket. But I personally didn't do that and have had no issues in 5k miles.

Thanks for the detailed response 96capricemgr, very helpful. Yes, if I weren't new to forums all together, I might have tried that.

It's all good stangtrader, that's what forums are for, right? Besides, it gives me another opportunity to post. Sweet!!

i dont see a t5 living very long behind an LS of any sort unless you never go over half throttle with it, i blew up a t5 in my cam-only 5.0 mustang, which probably only made as much power as a stock 4.8

Like the others said, I wouldn't use the t5. There's a reason they made a t56. Plus you get that extra gear.
As tthe t5 only came with the 305 third gen, it did come with a 1le package which was the 350 and t56. The treefifty also had over 300 ft/lbls of torque at the wheels. So it may last a little bit if you can get it on there, but once the mods fever hits your gonna wish ya didn't!

Thanks for the info 1988montecarloss, I really over estimated that tranny. Plus, that 2nd gear in the T5 seemed to hop, (I know it was only a 305, but that motor really hit well in 2nd). Definitely will look at a T56 or possibly an automatic, can't believe I said that. Any recommendations on auto trans'?

People love to hate it but the 4L60E when PROPERLY built can handle plenty. You get an awesome 3.06 first gear, torque converter lockup so you can run lots of stall and be comfortable on the street and overdrive so you can use plenty of rearend gear too.
