V-8 upgrade

Question for the forum? I have a '89 YJ with a Chevy 350 carb motor. What I would like to do is upgrade to a TPI setup. My motor is pre 1986, so I am not sure if I am able to do this add on? Does anybody have any experience with this or may have some direction to point me in? Appreciate any feedback.

I did it about 12 years ago on a 1st gen K5 blazer. Block and heads were early-80s that I had a machine shop build for me. All you need to do to fit the TPI lower intake is re-drill the 4 center intake holes to a different angle and order some beveled washers from Mcmaster. Edlebrock used to sell a tool for re-drilling the holes, that I wound up buying. I might even still have it somewhere. If you want I could dig it up and send it to you.

yes a couple bolt holes were changed. Other than that should be pretty easy to swap out.
