Engine, Tranny, TC swapping

One of my employee is swapping in a 350 inot his Toyota. He says he got the 350 from a 76 Chevy truck. Then he said that the tranny and tc came from a Bravada. He said it is a 700R4 and whatever tc. Well the tc will not work cause of the output being on the wrong side. What tc should he look for? He needs a Chevy tc with passenger side output. What would be the "ideal" tc to look for. AND anybody know what kind of problems he is going to run into trying to install the Bravada's 700R4 inot his Toyota with the 1976 350?

Thanks for any replies and help.

Laters, Ryan

Re: Engine, Tranny, TC swapping

T/Case that might work is the NP208... I'm pretty sure that is the one that was behind the T700s... Problems that I foresee might be no computer to control the tranny... Don't know that much about trannies but I seem to remember you need some sort of stand alone stuff to make it work in a non computer controlled vehicle...

700r4 is not computer controlled, thats the 4l60e and 4l80e.

Yeah 700r4's are cable operated, believe me. Broke the tv cable on my old 88' and 2 weeks later I lost 3rd gear.

Re: Engine, Tranny, TC swapping

What year Bravada? That might be a 4L60E, which is just an electonically shifted 4L60/TH700R4, depending on the year. As long as he can hook up the brackets and associated stuff correctly, the 700R4 shouldn't pose much of a problem.

700R4's had NP208's (2.6 or so low range) in 83-88 GM fullsizes and NP241's (2.72 low range) in the 89-91 K5 Blazers/Jimmys and 1/2 ton Suburbans. Both are chain drive with aluminum housings, but are good, solid, lightweight tcases.

Isn't the rear output on a TH350 the same as a TH700R4?

Re: Engine, Tranny, TC swapping

I was thinking about the same thing Andrew. the th350 and 700r4 had the same rear output shaft and bolt pattern for the tailshaft houshing/t-case adapter.

Re: Engine, Tranny, TC swapping

Yes the 700R4 has the same output as a TH350, so anything that came on a TH350 would hook up to the 700R4. This means that you can get the ever popular NP205 for it, which in my mind would be the ideal tc.

Re: Engine, Tranny, TC swapping

Alright, so, I have a TH350 from a Monte Carlo. So I could then mount an NP205 to that tranny? I want to build up a mid-80's Chevy Stepside, and I plan on taking a 350 and a TH350 from a Monte Carlo to put in. I can get an NP205 easily, so that would bolt up to my tranny then?

Re: Engine, Tranny, TC swapping

As long as the NP205 is configured to mount up to an TH350, the yes it will. It might be configured to mount to a TH400 or SM465, then you need to start swapping stuff around.

Re: Engine, Tranny, TC swapping

Since this is a car tranny (or two wheel drive) and has a tailshaft bolted to the back of it, you will need to check the length of the output shaft of the tranny. I dont know which length fits a NP205 (the voices in my head say 2" [img]images/icons/tongue.gif[/img][img]images/icons/wink.gif[/img]) but i believe that there are three different lengths of output shafts in the TH350's.
