Doubler Question

[THopper]

HELLO EVERYBODY!

Here is my question. Have a 91 tbi 350, 4l80, np241. I am in the never ending project stage and have come across an option and I'm wonder if it will work for me as a direct bolt in. I'm trying to buy a D60 from this guy down the road and he has a 203/205 doubler mated to a turbo 400. I know I have a 32 spline output with a length of 2.5"-2.875". How do I ID the 400 and adapter without pulling everything apart to see what he has exactly. If I can package deal this for the right price, I'd love it but don't want to get it and realize I need to change the front case or get a different adapter or machine anything.

While you never said what vehicle this is I might just add that a blazer NEVER had a 4L80E installed from the factory ever. Since this is a predominant Blazer site I thought i'd throw that out there for you in case you were either misled into what trans you have or just didn't know this info.

Correct! The only square bodys to have a 4l80 would have been a 91 3500 crew cab or a 91 2500 suburban. I have the 91 sub. Thats why I bought it in the frist place. 700r4's dont last to long towing or under hard abuse. Well, without putting a good amount of money into them.
