This summer I plan on dropping the stock 350 out of my '88 and having it reworked. I am putting 1.94-1.60 heads on. speed pro 9:1 pistons will be going into .030 bored cylinders. Also I am going to stroke it out with a milled 400 crank and throw long rods into it to pump a little more torque into it. Here is the catch. I am trying to stay within the ballpark of emmisions (which is why I am not putting 2.02 heads on it) and I really want to put an aftermarket TBI on it. Something like the edelbrock performance TBI with the matched intake. The chip that comes with it will help the emission issue a little but I was told that putting a dual exhaust under the truck wouldn't be a great idea because of emissions. Why build the block if you can't let it breathe? There are a lot of knowledgable people on this site and if some of you put in your 2 cents about the effects of this rebuild on emissions it would be greatly appreciated. Thanks in advance.
