Stop right now before you do anything else stupid. You also might want to run some of the other brilliant ideas in your head past the group here. If you have an assbackwards one like this... I bet you have a few more. Your pride may be hurt, but you will be money and time ahead.
Basically, you would have to add a few sensors, and wire them in to make your engine more picky, and harder to deal with. It would also require a 96/97 timing cover, swap knock sensors, etc... We tend to go the other direction, with putting an OBD-I PCM in the 96's.
MAYBE I should have asked this different so I would not be getting smartass replys. I'am doing an LT1 converson on my 69 Nova and was going to use my drivetrain out of my 95 SS thats why I was wanting to convert it to an OB2 .Thanks
