ditching the emissions
So in a couple of weeks I will be swapping a rebuilt 350 out of an old 1980 van and putting it in to my 86 z28.
I the engine didn't have any emissions on it. Can I just put this engine in my car with out worrying about ptting on any emission? I don't car about tha laws I just want to know if its a necessity to make the engine run in my car.
The only thing I know of that my computer controls is the tranny and the carb (i think). But I don't think the carb from the engine is computer controlled.
What would it take to make my car run with out emission?

The computer controls the carb primary mixture, and ignition advance. In order to do that, it needs input from both the carb and the distributor.
If you use the van carb, you have to use the distributor, too. If you don't use the CC carb/distributor, the ECM will not lock up the torque converter clutch.
Personally, I think it's a mistake to go away from the CC carb/distributor. It'll perform as well as a non-CC setup power-wise, and eclipse it for economy. Message: Don't confuse the CC carb/distributor with "emissions".
Everything on your factory engine will bolt onto the van engine. That would be the way to go, IMHO.
Have any plans to upgrade the exhaust system?

Already upgraded the exhaust with flowmasters, 3" and a new cat, I also have eldelbrock headers to put on when I do the swap.
what do you mean by CC carb? computer controlled?
If I used both the carb and the distributer that came with the engine, what would I need to do to make it work in my car?

12 volts ignition-switched to the distributor (same power wire the CC distributor uses now), a vacuum line between carb & distributor, and some way to lock up the torque converter since the computer won't do it anymore.
CC = computer controlled.

How does the torque converter lock up in a van from 1980?
I mean the tranny is still gonna be compuer controlled, so why would thier be a problem with the torque converter?
