info on the caddy thing for the longhorn...

[Longhorn Man]

Well, I spoke to the seller of the motor, and I am thinking he is wrong on what it is. *crossing fingers*
He said it is out of a 77 or 78 Eldorado...I'm pretty sure that means 500. (WOOO HOOOOO!!!!!!!!!!)
I been looking at a couple other options here too;
Being a one ton with no gear options, I think (have not verified it yet) it'll be having the 4.56 gears. Caddys don't like to spin, they like to grunt, so this would make a very unhappy torque motor.
The 200-4R overdrive was vere popular in the A and G chassis cars, and the OD monti carlos all had dual patter over drive trannys in the '80's. (fits both chevy, and all the other GM engines)
So I started wondering about the torque converters...they are drilled for the larger pattern in the fly wheel. (TH400 holes) Which, coincidently, was mounted behind the caddy motors.
I need to look at the fly wheel on the motor I will be getting (dang near a done deal), if it had the raised mounting points (like a chevy flex plate) then all I'll need to do is find a 200-4R out of an olds...they used the same set up, while most (if not all) the others had flat flexplates.
A cool thing about this is, most junk yard owners don't realize the difarance between the 200, and the 200-4R...no one buys either one very often.
There are 2 draw backs I can see as of now...
1. This tranny still runs the stupid pickey T.V. cable...I'll have to probably pay some one to set it 100% correct. Forget the Chiltons way...I want oil pressure readings. (the shop i work at just lost our tranny guy, we refer ppl to another shop for that now....huge bummer)
2. Converter lock up. I'll talk to whomever sets my TV cable, but I know B&M has a kit to controll the lock up...a little under dash 'black voodoo box'.
3. I don't know about shifter notches...as in, the extra position, will I lose 1st gear manual over ride? (as in low 1)
A couple good points on this tranny....
1. My truck has a TH350...the 200-4R is the same overall length, and uses the same yolk.
2. the mounting pad is at the TH400's location...just move the X-member since these were available with the TH400.
3. Mechanical speedo hook up. (you guys with the 700 R4 know what a headache an electric speedo hook up can be)
4. Supposedly, the 200-4R is a little stronger than the run of the mill 700 R4...but I have no proof.
Any one have anything to add...any thing good, or bad...looking for posible problems so i can figure it out now.
How about opinions...I know y'all have them...share them with me.
