[QUOTE="big dad, post: 15878066, member: 100697"] OBD1 requires a 60 pin PCM, OBD2 is 104 pin PCM, you would need to change the harness which really isn't very practical or necessary unless you're going too a coyote engine. You can still find sources that will provide a chip too install if you provide them the necessary info. When I did mine I got a chip from Motorvation through Summit. If you plan too make some upgrades like HCI also go with larger injectors, I would recommend 30lbs. and a 75mm MAF calibrated for said injectors. Make that 5.0L breath from the intake thru the exhaust, that includes the EGR spacer body which I would retain also and a 75mm throttle body. I would also suggest a TrickFlow 170 HCI kit. And don't forget a hi-flow fuel pump, 190lph should be sufficient. I did all of this to my 86 and the results were stunning, especially the throttle response and how quickly it revved to redline.
