Have 302 w/ mustang header and seem to have lost power
I bought 89 150 Custom, modified by NASCAR guys, upon which they put on Mustang header, and false side dual exhaust. One pipe of exhaust finally broke free due to intense stress on hangers; thankfully not killing anyone behind me from the cart-wheel expulsion. I had true dual exhaust system installed - A-1 quality job, can do pull ups on piping - but seem to have lost significant power on 302. Believe the total release of any backpressure may have contributed to loss of power, perhaps because the valves may be floating due to uninhibited exhaust discharge. Do you have any suggestions?

Try taking the number off the engine and see if the dealer can search it up. I doubt they only put it in one car model, but the number on the engine should match the frame. Get where I'm going? As old as it is, I wouldn't expect anything though.
ok Ed I found you again and more info , your ignition is point, unless modified style,mallory is a hi out put ignition system ,that gives great spark control,=power goes to coil and is sent to distrubiter to the points to the rotor to the plug wires to spark plugs.NOW you can get any unit of wiring but not the whole car that would take 100 of pages ,or you go and buy a SHOP REPAIR MANUAL for about 125.00 or more what you can do is type in (images of wiring diagrams 1967 mustang (motor size) (and area you need ) ) like ignition ,blower motor,head lights, and look at site ,and lastly join a mustang car club online those guys EAT AND BREATH mustangs and can lead you to all the info you could ever want . I REALLY hope this gives you what your looking for.
You'll need the K-member from a 94'-95' v6 or GT, along with the correct motor mounts. once you have that it should drop right in. But there are many more parts you'll need to make it work like a 5.0 tranny, exhaust, wiring, pcm, radiator, and maybe more. Look in the Ford Racing catalog and drop a 4.6L Cobra motor in there. A lot fewer parts to buy. Also if your state has car inspections the 5.0 is not OBDII, and should only be attempted if its going to be a "race only" car.
That's because the 302 and the 260 don't share the same accessory bolt patterns. If it's a dealer installed AC the mounting may be "custom". If you still have the original engine, transfer the bolt hole positions, drill and tap. Good luck. Measure twice!
The O2 sensors are mounted into the headers. If by aftermarket exhaust you mean a cat-back exhaust system with midpipes and mufflers, then the O2 sensors are a non-issue - they won't be touched. If you are doing cat-back, headers, and maybe high-flow cats, the O2 sensors will just screw directly into the new headers - they'll be set up to receive them.
Get on the internet and go to Jeggs or Summitt and you will find all kinds of aftermarket suppliers for the exhaust. Or, just go to Gibson Exhaust or Borla. They all have these kits. They are not cheap though.
