th 350 turbo or 700r4?????
I was wondering if someone could lead me in the right direction here. I currently have a 700r4 tranny and was wondering if I should put in a 350 turbo? I am in the process of installing a SD 360 engine (from a 305) and was wondering if the 700r4 will hold up and/or do I need to make changes to it such as adding in a shift kit (stage), and converter? Or do I need to change to a turbo 350? If I need to change, what needs to happen on the 350 for the sawp? I know I need a long tail (9" to keep the drive shaft), and a cross member http://www.spohn.net/?action=product&pid=1176. Will I need a torque arm bracket http://www.jegs.com/p/Hurst/746223/10002/-1/10531 or do I need both? Would there be anything else that needs to happen for this swap? Will my automatic shifting plate still line up with my indicators (ie, p,r,n,d,2,1), will my speed-o-meter still operate properly, or are there kits for this as well. Any opinions, suggestions and/or guidance will be greatly appreciated!
Sorry for all the dumb questions, and thanks for the help!

Thanks for the info! It is very useful! So, what did you end up doing? Keeping your 700r4 or put in a th350? and if you did put in a turbo 350 where did you get it and how did you make out?
Thanks!
Thanks!
