Default lt1 t56/ ls series block

What do I need to do to run a T56 from a 94 camaro with an LS series motor. The motor is the 6.0 iron block (lq4 i think??). Do I need a different input shaft? I assume an LS bellhousing, but other than that, any help would be appreciated.

Bellhousing, input shaft and front plate are different, requires total disassembly of the trans. Not really worth the hassle IMO unless it needs torn apart/rebuilt anyway. Probably easier/cheaper to sell the one you've got and pick up an ls1 t56.

doesnt require TOTAL disassembly, it needs a diff bellhousing, a diff input shaft, diff hydrollics and a diff front plate as said, but total dissassembly to change 2 parts? you take out the bolts on the front plate pull the input shaft and front plate off and put the ls1 input shaft through the ls1 front plate new rtv silicone n bolt it back up. done, with that part. worth it? no, doable? yes, better to gt an ls1 transmission? yes.

I should mention that i am swapping this 6.0 into an rx7 and everything will have to come apart anyway, i had purchased the t 56 to put into the camaro, but now the camaro is gone i have the trans just laying around. Plus the shipping to hawaii is outrageos, is this something a decently knowledgeable person could do, and where would i source individual parts like that, the bellhousing would not be hard, but i dont want to go through chevy for the input shaft and plate, thanks. Also, why new hydralics? even with my application in the rx7?

A T56 from an ALUMINUM LS1 will work on the Cast Iron 6.0 right?

the lt1 and the ls1 use diff style hydralics, one uses a push method the other uses a pull method, as for swapping the input shaft and front plate, its easy VERY easy how ever long it takes you to pull the bolts out of the front plate pull the input shaft out, it just rides on bearings in the transmission i think it took me 10 mins to pull the front plate and input shaft out, then it will take a while to clean the old silicone off and put new on then about 10 minutes to bolt it all back together, as for the t-5, i have no idea. also if you do swap them out i might be interested in the input shaft, if its in good shape

Yeah, i bought the t56 for the lt1 because i was going to use my 94 z28 as a donor, then i found the 6 L iron block for a decent price so i figured i would sell the car whole, not i have a t-56 that will be going up for sale. And when i bought it i was going to convert from auto so it has the pedals, slave cylinder, hydr lines and hurst short throw if anyone is interested, ill be putting it in the classifieds i guess.

Or maybe ill stick with the LT1, wow having limited funds really sucks, you gotta do so much planning before you buy anything

lt1 input shaft is different from the ls1 shaft length wise also the front cover is different along with the bellhousing to convert an lt1 to an ls1 you need A. ls1 input shaft B. ls1 bellhousing C. ls1 front plate and vise versa if converting a ls1 transmission to a lt1.
