I've got a 1985 s10 blazer 2 dr, and it already been swapped once to a tbi 4.3 and I'm really wanting to do the 5.3 swap, I have the engine. Trying to get a harness and pcm as of now, I'm gonna be using the 700r4 trans and I'd be nice to get some tips on what to do with fuel system, possible help with diy standalone harness, and just general stuff thanks in advance
Going to have to follow along with this one. I have a serious soft spot for those trucks. I have had 3 just like it. All black, 2 door, 2wd. Can't wait to see how this one turns out

Thanks, I actually sold it once and I somehow but some stroke of luck found it and bought it back just recently lol... but I'm putting it up in two weeks to start the tear down!
Thanks, I'll keep this updated as much as possible... I'll be running the truck intake, what one is a better choice the 700r4 (my truck has) and 4l60e? And why?
Just run the 700r4.
The 60e is a great trans and works very well with the stock PCM, but its basically just an electronic version of what you already have.
I run a 700r4 in my 68 truck. I have had very good results with it. BUT, you will need a TV cable and bracket for that cable. GMoverdrives.com has the cable and bracket as a
kit. In my opinion, it is a little pricey, but it works and is the only kit that I have been able to find for this application. You cannot use this trans with a DBW throttle body and have any trans longevity. The 700 MUST have a TV cable to live properly. Please read LIVE PROPERLY.
But get a converter to match the engine and have fun. I love these cars also.
