i have a 302 shortblock that i am told is from a 91 truck, with a stock truck cam and cast .040 over federal mon-something pistons. I am told it is non high output (whats that mean?)...So give me reasons why this would have suposedly came out of a 92 mustang gt (bought as a 92 mustang 302 motor with 60k original miles, got home and found all this out from someone) thanks for your help in solving my dilema

I think non high output has mostly to do with the firing order and the camshaft (which are linked). Not quite sure what you mean by the rest of your question, but it wouldn't have been too hard to put it into a mustang. If it still has the truck cam then you'd just have to change the firing order to the non HO order.

sorry if that question sounds confusing....What happend was is i bought what was listed as a "302 shortblock from a 92 mustang gt with 60k original miles, ran good when removed" i bought it, had someone check it out, and they determined that it is a 1991 ford f150 block with a stock truck cam and had been bored .040 over with some cheap cast pistons. He also gave me some heads that go with it. He swears that this came from a 1992, but i know he is full of sh** and he refused to refund my money. I am going to file a civil suit against him, and want to know why it would be very unlikely for this motor to have come from a 1992 gt.

What information was used to determine the year and application of the block? Casting numbers can be used in many different applications, in fact 94-95 Mustangs and F150s used the same longblock assembly, I believe... Correct me if I'm wrong here, please! I'm pretty sure the trucks use the same E7TE heads as the HOs at least (I think the T in the number means it was designed for the truck engines maybe?).

At any rate, if the casting numbers say it was made in '91, it could have ended up in a 91, 92, 93, etc... until the stock was used up, so that itself won't really help a whole lot I don't think. Good luck figuring out what it is for sure, at least you know that it's not a stock bore.

+1 on the firing order being different. One time we sold a f150 motor for a Mustang motor...shop knew we did that....but they didn't know about the FO...neither did we till we read some notes in our computer!!! Hehe...they were pretty mad for about an hour because the motor ran awful.

so if you put the wires in the non h.o. order, it would run fine, just not as powerful as a mustang cam?

and if a h.o. cam was added, this would be considered a h.o. motor then? also if the heads are the same, are the springs and such the same also between the truck and stang?

I would wonder if the non HO was a flat tappet or roller cam

I wanna say those non HO years were around 79

i was told its a non-h.o. camshaft, but how can you tell w/o part numbers?......also i just noticed that the distributer has a connection like the 94-95's, which is also the same as 92-95 trucks i think (more proof that i got scammed by this guy)
