350 sbc + t56 swap
« on: September 11, 2015, 06:53:29 PM »
Hello guys, long time reader, first time poster. I have done a search on this topic, but i havent found the exact same situation im wanting to do. My truck is a 75 c10 swb stepside, floors will be done on sunday and i have the sbc sitting waiting for the front clip, cooling system, and most importantly the trans. I was originally going to go with a 700r4 but it is always more fun driving a stick. I have had a few friends that have ran 700r4s before and love them for the OD but they fail after a year or two of abuse. My engine will be a 355 roughly 350-375hp and around the same on torque.

So my question is how should i go about adapting the t56 trans to the block? I have heard of adapter bellhousing make by quicktime and such. I have also heard of adapter plates in between a factory muncie t10 bellhousing and the t56 trans case so you can use a factory style flywheel, clutch, and pp setup. I like the second option because i have a muncie bell and billet flywheel.

Which option would be best? Has anyone done this before and used both or either? Which would be safer? And i am having major problems finding a transmission locally that doesnt cost $2000+. Junkyards around here rarely see any ls camaros with a t56.

If you get the latest issue of car craft magazine, there is an excellent article in there on t56 transmissions. And the different types of adapters and set ups. May help point you in the right direction.

Also keep in mind some lt1 camaros came with t56s as well, and would not need an adapter
