Hi everybody,
I am very happy to have found this site, and I have queries.
I am the very proud owner of a 1982 Lincon Mark VI, 302 AOD, with about 144k on it.
It was purchased new by my Grandfather, and I am very happy to have it. It is in very good original shape. Not flawless, but damn close.
Here is my problem-
the original engine bit it and I was forced to find a replacement. Given the original engine's output of around 140hp, I took this as an opportunity to get it to the 180-220 hp range I feel it should have always had.
Found a 95 302 HO in good shape, from an automatic Mustang, for 200 bucks. Jumped all over that.
I am mechanical to some degree, and prefer to work on my own cars, but this is way beyond anything I have ever attempted, so I enlisted the services of a friend/mechanic/mechanical engineer to do the swap for me. He managed to get rid of all the extraneous smog shit, and get the new motor in.
Here is the issue- for ease/ intention of keeping it as original as possible, he retained as many of the old staock parts as seemed plausible. The Mustang engine has been carbed, so he removed that intake, and used the original tbi, exhaust manifolds and all sensors.
It runs. Not well. It starts easily, and if youstand on the gas it will build revs, but after 15-30 seconds, they begin to fall very steadily until the engine dies. If you pump the gas continuously, you can keep from having to restart, but there is still no power to speak of. I tried driving it a short distance as is, and was able to do so, but with almost constant shifts in/out of nuetral to keep the engine running.
I think it is running rich. I don't know how that's possible with computer controlled tbi, but as I said- I'm no expert. Thought it might be too much back pressure as it is single pipe, and it comes out like a leaf blower.
Cut off exhaust at cat to see if that cured it, no luck. it did improve a bit.
I am trying to figure out how to get this thing running right, and I and my guys are at wit's end. Please, please- any suggestions would be most welcome.
Short notes:
As mentioned, it is not setup as SEFI even though that was the original for the motor. It is not carbed, thought that is an option but I would prefer to keep the fuel injection intact.
Still single exhaust.
Runs, but smells rich and bogs down very quickly.
Ok- I hope I get some hits.
thanks guys!
Bob
