I've got a 93 T/A that was flipped in an accident and I want to use the engine and tranny in my 80 T/A. I haven't started the car since I've had it but the guy I bought it off of swears its a good engine. The reason I haven't started it is because the key was lost and I drilled the key switch out enough to turn but broke the wire coming to the switch. I'm going to by pass it and try to start it but I was just wondering if these cars had a safety switch that kills the engine when flipped. Ive heard alot of people say if it ran on its top the motor can't be good. Thanks

 

Never heard of an f-car having such a switch. Very doubtful.

 

Even without it I would say the car would die within a second from all the oil being shoved into the cylinders wouldn't you? I don't want to throw it in there and then have it spin a bearing in a week lol.

 

it flipped? im assuming the car was running while it was upside down until it stalled as no one is going to think to turn it off during an accident. all the crap in the bottom of the oil pan went to the top of the motor, sounds like your in for a lot of headaches unless the car was given to you. either way, i would tear it down and at least replace the bearings and pistons while its apart

 

if you pull all the spark plugs, can you spin the motor? without a borescope, i'd say to pull the plugs, change the oil, spin it a fews seconds with the starter hooked up to some power, do a compression test, then cross you fingers and hope its all good. if its in your budget to do gaskets and tools, tear it down and inspect it. IIRC, the fuel pump runs off the oil pressure switch after the engine is running, so if the car flipped, the fuel pump would have shut off once the oil pump started sucking air, killing the engine eventually.

 

You're going to need a vats bypass module if you don't have the key. The car should've died instantly being turned upside down because of the loss in fuel pressure. If the engine was good before the flip, it should be ok after.
Oil is not going to gush into the cylinders, it may weep in after a day or two.

 

F-body cars have no fuel pump circuit to the oil pressure switch.

 

Well according the guy I bought the car from they ran the engine after the accident and it ran perfect. I plan to start it and let it run for quite a while before I ever pull it and attempt to put it in my car. So more or less if everything starts up and runs fine while its in the 93 I shouldn't have any trouble putting it in the 80?

 

There is no impact shut off like on a lot of Fords. If the car was on its roof, it wouldn't run for more than a few seconds since the fuel pump is going to stay at the bottom of the tank but the fuel would not. It would probably run until it ate itself if it was on its side and had a decent quantity of fuel in the tank however.

If you lost the key, you will have to bypass the VATS theft deterrent in order to see if it will run.

 

No they don't. I flipped my 95 and landed upside-down. Ran for a good min or 2 until I turned it off. Let it set for a day, and it turned on fine. Fixed it up, green car with a black door. Jacked up the roof with a 4by4. Used it to deliver pizzas and raced everyone in town for 2 years. Still have the car, just bought another a few years ago.

 

We only have a little check valve so gas doesn't pour all over and burn your *** to the ground.

Negative chief. Fbodies are dumb and whatnot.

Seems legit. I would trust the guy you bought a car from.

 

It's called an inertia switch and f-bodys do not have them.

 

I do, my pcm is wired through it.

 

You're a towel.
