I have read and read and read the forums, but can't seem to find a straight answer. I race 2.2 cavaliers on a dirt oval, and have done some extensive research, but I still find myself with questions. I have wound up with a car that has a 99 bottom end, a 96 head, and a 96 wiring harness that has a rough miss to it. I was told the engine was running smooth when first put together, but developed this miss before they got to race it, and just brought it home. I know it was being ran on pump gas, which I personally never would have done in the first place, and there is also a heavy exhaust leak where the manifold bolts to the pipe. I'm going to do compression tests and check the injectors this evening when I get home, but is it worth fooling with? Is this combination even capable of running, or am I beating a dead horse? If there is something that could be changed to make it work, or just some kind of direction other than what the typical guy would know to look for. I know the timing notches are different as of 98 on the crank, but would that make it miss? If so, could i put the crank from the spare 95 motor I have? Any input will help.

You've never seen this?-

2.2 Growing pains

It's the most complete 2.2 interchange/spec available. Since I've never tried your specific setup, I can't tell you for sure, but this article will point you in the right direction.

I've heard a few people say that the cranks can be swapped without problems from the ECUs.
That piston/head combo is really high compression; I wouldn't suggest pump gas.
