Unhappy Noob needs help! 86 mustang svo motor swapped to 71 5_speed carb 302 v8

please dont get upset with any miss use of engine lingo
ive worked on small motors before but car motors a new game for me.
(please dont hate me for the motor swap i didnt do it! lol)

so let me start off with whats going on with the car...

got car in a trade not fully done
1986 mustang svo
the motor and tranny were swapped out with a 5-speed carb 302 v8 that came out of a 71 comet.
motor and tranny installed
already has mechanical fuel pump
eletric fan(not connected yet)
motor truns over but wont fire because it needs a new distributor
needs H pipe for exhaust
wiring is all over....

ok so now that info is out there
my questions are..

how do i wire the svo's EFI turbo wiring harness to the carbed 302 v8?
ive been told all i have to do is run power to the altinator, starter, water pump....<

what type of distributor should i buy for this motor?
the last owner told me he had to change some lil black box inside the distributor<

last owner said he belives the coil pack may be dead and the distributor may be fine for can i tell he is giving me 2 of them so i would like to test em...?

i have no idea even wich directon to begin here.... i have gotten the oem wiring diagram for the 86 svo i am guessing im going to have to find the 71 comet wiring diagram too but what then?

any help, diagrams, info, pics ANYTHING will help like i said im new to working on car motors....

thank you in advance everyone!

My suggestion to you is to use the "search" feature and research any topic or thread about a 4cyl to 8cyl. swap. Being new to this, you'll probably learn alot more that way. You'll be reading for hours, even days, but it's all been covered here before. There is a ton of fun info on this subject, tips, does and don'ts, etc. You just have to look for them. Good luck

And welcome to the forum, congrats to you for trying to tackle this project. I think you'll be happy when it's done.

Oof. If it were me, I think I'd abandon the SVO wiring altogether and start from scratch rewiring the setup from the ignition switch to the engine that is in there now. It isn't that complicated to get the old carb setups to run but having it interface and work with the factory gauges will take some doing though.

As far as what distributor to use, I'd go with a factory Duraspark II setup. They are deadnuts reliable and simple to install. Verify that you have the distributor installed correctly because distributors don't go bad too often so my guess would be to check the coil first.
