Help! 302 Block ID
I am newbie here so please bear with me. I recently acquired a 302 out of a 95 Mustang (supposedly), and the seller said it was a GT-R engine. I'm not familar with this. A few buddies and I have tried to locate the ID numbers but all we can find are a few 2 or 3 digit casting numbers from the foundry. There are no numbers what so ever on the right side towards the lower back end. I've also been told by some Mustang guys that I could actually have a aftermarket R-Block that Ford Motorsports sold as race engines. Is there any way to confirm this? I'm going to have a complete rebuild done so I can drop it into my 48 F-1 that I'm rebuilding custom. But I need to figure what it actually is so I can figure out what computer and electronics I'll need. I'm hoping to hook it up to a AOD out of a 91 Crown Vic that I have. Does anyone see any problems with that? Thanks for any and all input.

Without any casting numbers, I don't know what you have.
There should be a casting number by the starter, something like:
**** - **** - *
should be letter, number, letter, number - four numbers - letter
If your sure its a 302, you won't have any problems bolting it to the aod. Good luck with your project

jw,
I looked again for the umpteenth time, no numbers at all. I was told that if it is a aftermarket race engine it may not have any numbers on it. (I find that hard to believe.) I stated earlier that it was a 302, the air intake emblem say's 5.0, does that make any difference? I'm not much of a mechanic, more of a designer than a nuts and bolts guy, but i'm learning.
Under the intake it has the Ford script in the center on top of the block. It also has XXX between the 2 & 3 ports and between 6 & 7. Does that mean anything or is that a typical casting on Fords?
Let me know if you think of anything else. Thanks for the input.

Got me, I tried to find something on GT-R and found nothing.
5.0 stands for 5 liters, which is what 302 cubic inches comes out too.
Try this forum www.corral.net they should be able to help you, thats a mustang specific website.
If I come up with anything, I will let you know. Being there is not a casting number near the starter (which is where they are), that would make me think its aftermarket. Good luck finding out what it is, later
BTW, what numbers on the block did you find?

All I could find is:
On the right rear bolt flange there is FISE with 88 directly center and under it. There is also a #1 laying down about 3/8" below that about twice the size of the other letters. The #1 is about 7/16" long.
On the left rear bolt flange there are two circles with numbers (like a clock), the circles are about 7/16" in diameter. One circle has a 1, 3, and 2 the other has 1,5,7,4, and 6. There is also a larger O under that, like the #1 on the right flange.
That's all I can find! arghhhhhhh!
Thanks for your help.

If its F 1 S E. INstead of the F I S E. That you wrote.
F= 90 - 99
1= year ~ 1
S= thunderbird
E= engine group
So appears it is a 91 thunderbird block.
I looked under replacement blocks and found an F1SE was put in explorers as well.
302/5.0
V8
96-11/96
P
Explorer, MFI, Non Roller Cam, Block #F1SE, Head #F1ZE-AA, Knock Sensor inBlock, firing order 13726548, “GT” cast next to #1 sparkPlug
So if I had to update my guess, you have a stock block. Another thing I found the 3.8 v6 were stamped F1SE as well, so it must be a production block number, IMO. later

yeah i was going to say that XXX is on all 5.0L roller blocks. You sir have a stock production block, theyre good blocks too so dont worry about it. I have the same block bolted to an AOD w/shift kit going into my mustang. It should haul some booty.

I am a member at www.mustanggt.org and www.corral.net, to the best of my knowledge there is no such thing as a GT-R block, and I believe 94 was the last 5.0 in a mustang, in 95 they changed to the new motor (I think), so I think you got scrooged, especially by looking at the block number, its a 5.0 out of a thunderbird or explorer......but that still isnt a bad thing, you were just lied to

I drive a 1994 F-150. I've also found the F1SE on the block but my firing order is 13726548. The book says that this is the firing order for all 351's and 1995 and newer 302's. My intake says 5.0 EFI. There are no numbers anywhere by my starter which is where the books all tell me to look. Let that all sink in and tell me what I have. It looks like I have a 1994 truck with 1991 castings and 1995 firing order. ALL ORIGINAL!!!

Casting number is the same for multiple years after the first year it comes out....so F1SE is used for 91 up past your 94. F1SE is a roller 302 block, basically identical to all 85-93 mustang blocks.
