I have a 1988 thunderbird sport coupe w\302-HO: I just got the motor rebiuld, went 30 over, change heads to Mustang GT, I put a ford racing performance cam, I also put a Cobra jet GT upper and lower intake manifold, installed bigger injector and put cold air intake. I'm planing to put headers on but it does not have ports for O2 sensors. Ok so should I remove the O2 sensor with the air pump, I already bought a smog pump eliminator pully, Also I live in a county that deos not have a smog law and the elevation here is at 5000ft. So what need to be done to jumper out O2 sensor and what eles needs to be done Roman

 

Not to bum you out - but you're not done yet. You need to recalibrate the EEC IV computer to properly distribute the fuel and air mixture,etc. There is a company that sells custom chips for onboard computers - or try an aftermarket harness. The O2 sensors could be put into the headers with some welding or else it may act weird with just a jumper - an electronic and engine harness wiring diagram would help to decipher the correct way around it.
