What i did on the tranny was picked up an LT1 t-56 (i had a sbc at the time) and 2nd gear was bad (typical on these), so when i did my LS swap, i went too Rockland Gear and ordered their kit to convert. I picked up the tranny for 900, the kit was 400 and the rebuild kit was 700 ish if i remember correctly. I paid for labor which was 700 or so and ended up buying two input shafts (one for the LT which i still have brand new and one for the LS)
So, if you can source an LT (800+/-) the kit for 400+/- and the rebuild kit (it turns the tranny into a magnum) for 1200+/-, you have a very stout tranny and waaaay stronger than a stock LS tranny....
