Ok, I am a weee bit out of my element here, and need some help. I know a few of the guys on here are into old muscle and might be able to help me out a bit on this.
I'm swapping a 302 into a Nissan S13...

A little ambitious, but it has been something I have wanted to do for a while.
I picked this up last weekend, and am in the process of putting it into an 87 Nissan shell:
It's the engine and transmission from an 85 Mustang 5.0. Chose an engine from an 85 due to the carb for simplicity, and the roller cam! It also came with a T5 attached with a brand new clutch, flywheel, etc. I got the engine complete from a running car for a song!
The engine is in (no pics yet, finished installing it in the dark of night, all while getting eaten by mosquitos), and is getting plumbed this week. (oil, gas, water, etc)
So here is where I need help - the engine is carb'd and has a distrubtor with a coil - something I really haven't messed with before.

Been looking online at swaps, and to figure out what I need to do in order to make this thing run. I thought it was as simple as hooking +12 up to the coil and starter, fuel to the carb, blocking all the vacuum, and letting her rip, but it doesn't sound quite that easy... (or is it?)
Been looking around online, and it appears that an HEI distributor would make life much simpler - just bolt it in, add +12 and tach, wire the plugs up, and away we go... Has anyone messed with one of these?
And for the carb/vacuum... Do I have to hook any vacuum up to the carb to get her to run? Or can I just block it all off?
I will admit, I am a bit out of my league, but would appreciate any help. I really want to get this thing running, as it will be a monster!
