5.3 Vortec to 91 Blazer with 700r4

[Zoomad75]

Ok, I've been all over the net looking at info on putting a 5.3 in front of a 700r4 trans in my new to me 91k5. I'm getting confused on some of the details. Main ones being for the tv cable and convertor lock up.

My 5.3 has the DBC (cable) style throttle body. I've found the kit by Bowtie overdrives. The question I'm racking my brain on, has anybody set up a tv cable to the 5.3 throttle body without the Bowtie Overdrives kit?

Next up, I've read a bunch of threads from multiple forums that indicated a lockup kit would be needed in this application too. Keep in mind this is a 700r4 that originally came in this 91. I've had a lot of dealing with the th350 and 400's but missed out on the 700's so it's foreign to me. I've got it in my mind since this truck came with the 700r4 it's already set up for convertor lockup, but am I right? If not then I would assume I need the lockup kit that TCI or Bowtie overdrives sells.

Just a little background, I'm using an aftermarket MEFI4 controller and harness to run the 5.3. So I don't have to go screwing around with tuning the trans and resulting codes out of a stock pcm.

Any ideas would be very helpful as I'm at the parts buying stage of my buildup. I have a tight budget and only want to do things one time. Thanks
