[font size="1" color="#FF0000"]LAST EDITED ON 23-Dec-00 AT 07:00 PM (EST)[/font][p]It is quite possibly a Mustang engine. When Ford did the roller conversion, the camshafts had the 351 Firing order.
Look on the engine for a part number, that will at least give you a start at identifying it. Look for a part number that starts like this on your block.
E8TZ
The year of production will start with a letter, and the second position will be a letter. And the third position will usually denote what it was in, such as T = Truck
Ford's part numbers run like this. And the number after the letter prefix will be the year, such as E8 = 1988
A = 1940's
B = 1950's
C = 1960's
D = 1970's
E = 1980's
F = 1990's

Question on a 302
The 5.0L H.O. had a different firing order than the regular 5.0L's which is most likely what you have. It is actually a hotter engine than the truck engine. It has higher hp, somewhere around 240hp, but lower torque, somewhere around 220ft/lbs.
My uncle has a 1992 Thunderbird with the H.o. with really high gears, it's going @ just above 1000rpm at 70.
It can really haul at high speeds though.
Pastmaster's 1993 XLT 5.0 E40d 3.55LS Normal Cab/Long bed Loaded from the factory with aid of...MSd 6a ign/s.p. wires, blaster coil, Hypertech Chip, K&N filtercharger, Cat-back dual exhuast w/o mufflers, 3.5", echo tips, Accel distributor cap, Dark Mocha over light mocha. 5% Dark tint, Alpine Cd player/remote, Pioneer speakers.

Good deal? I would say it's hot. Because you stole that thing man! $150 bucks for what could likely turn out to be an HO. Yeah $150 is a good deal.
Kind of like the good deal I got on that seat huh, pastmaster?
$50 bucks! And it is the Flight bench with the extendable headrests. And in mint shae (except for a couple of small tears.)
Pastmaster I'll try to get some pictures tomorrow and get them posted in my old thread!

It really depends on what kind of pistons you want.
Summit racing carries some really good brands.
Silv-o-lite: 8.2 - 9.7:1 Compression Ratio (Flat Top) $186.99 Set
Or, they have a complete kit to take you engine up to a 306 (probably with an overbore), complete kit, pistons, rings, gaskets, crank, and all the bearings & connecting rods for $879.95
So I guess it reall all depends on what you want to do with it.

Ford might stock it, It would be better than a parts house cheapo. Plus they might make you buy a whole set. It all depends on who you know and how nice you talk to them if you don't know them.

Question on a 302
You have a 1980 block w/ a 351 firing order? I had a 1980 block w/ a 351 firing order and 1985 heads. It came as a rebuild for my dads 67 Ranchero which eventually made it to my yard. I didn't know about the 351 firing order and my buddy (who was mentoring me)being a chev kinda guy didn't know the firing order, so we looked up the 302 firing order and went for it. It ran badly of coarse till we were clued in about the 351 thing. My point is that it was put together from parts as a rebuild, and I didn't know what cam was in it. Camshaft grinds make a big difference in HP... so unless you know what you have, you can't make a good approximation.

Ok, you have a windsor firing order, that means that if its not a HO, somebody put a windsor cam in it. It may be a stock windsor cam or after market, either way its an upgrade from a stock 302 cam. Stock windsors have a higher lift. Changing to a windsor cam is an easy thing to do: pull old cam, install windsor cam and change to windsor firing order.
If you have either motor, and you can't find a cam that suits you, check the cams for the other motor and you may find what you want. They are interchangable so long as you fire the motor to the cam you have.
