    Default Is my engine stock?

    This is my first post and I am a complete noobie to thsese cars so sorry for the silly question. Anyway I recently bought a 1985 Mercury Capri RS with a 5l 5 speed and am very happy with it, however the engine dosnt look like any Foxbody engine I have seen. I am hoping one of you would be able to tell if it is the same engine it came with from the factory? Name:  IMG_0160.jpg

    I can't speak to your specific car of course but that looks somewhat like a 1985 5.0 HO engine based on the picture. A true '85 5.0 engine would have had an aluminum intake with the Ford logo stamped in it. That may be the correct intake only painted blue, I can't say. It has had the smog pump removed and it did not come with those electric fans. It would have had a clutch-type fan and a different dual-snorkel air cleaner assembly on it. Also the engine would not have been blue from the factory so either someone has painted it in place or it has been rebuilt/replaced at some point. Your car appears to not have AC and that front engine dress would be correct for a car without AC as well. The valve covers would also be correct.

    As well, somebody put an Edelbrock/Carter carburetor on it.

    Thank you very much! I have also found this stamp on the manifold although I doubt ot helps much.

    There should be some numbers on that pad on the other side of the block. Those numbers will have some of the same information within the v.i.n. if you are wanting to know if it could be an original engine block to the car.

    I cant find any numbers on the other side besides an R stamped behind the valve cover.

    I have just found paper work from the previous owner who had it in for a wheel alignment, balancing and checking the timing. It lists the engine as a 5.0l V8 M OHV 4bbl but im not sure if that would just be going off the VIN number or not?

    Engine height looks correct for an 8.2 deck height block which is factory - motors like the 302 and 289 were 8.2.

    Modifications are very popular on Foxbody Mustangs and Capris. Impossible to know what it is internally without tearing it down and inspecting everything.

    You could pull a valve valve cover and see if there is evidence of aftermarket rockers, or springs, etc.

    If it's not broke, don't fix it. 302's usually run great with a properly sized and jetted AFB/Edelbrock carb.

    Ok, thanks for the input. The carb is a weber BTW although that probably dosn't matter.

    What about this small block Ford V8 does not look like any other Fox body engine you've seen? If you're used to looking at all the who-haw atop of the EFI engines, then I get it. Otherwise, the engine in your first photo up there is run-of-the-mill SBF fare.

    I believe Weber was contracted out to make the AFB style carb for Carter and then Edelbrock. Most everyone identifies them as the Carter AFB.

    That makes sense. Like I said I'm a complete novice when it comes to these cars and their aftermarket parts.

    I used to know a guy who had an 84 Mustang with a 5.0l however after looking at some pictures on the internet it was probably an EFI. My cousin also owns a fox however his engine looks nothing like mine and after asking he said it was heavily modded. I knew it was a Ford 302 but I wasnt sure if it was a mustang/capri 302 if that makes sense. I also didn't know if there would be a way of identifying it as being the original engine from the car like a VIN number.

    That is a non-a/c car from the factory. The heater hoses would have come out of the firewall behind the intake manifold if it had a/c. This is good because it makes changing a failed heater core a much easier job. That intake manifold has likely been off that engine as well - that is not a factory bolt in the picture. The engine code is the 8th character in your VIN, it tells you what engine the car left the assembly line with.

    I have the VIN number for the car and after typing it in to a decoder everything checks out. Its a 1985 Capri RS with a 5.0l H.O. 4bbl. I was hoping to find a VIN number on the block its self although I would probably have to take out the motor to see it, right?
    Thanks!

    The vin number should be right at the back of the intake manifold ON TOP OF THE BLOCK. you should see a pad on the drivers side with some numbers stamped in them. You may need to clean the pad with some sandpaper to read the numbers.

    Alright I will check when I get home. I also looked up that number on the manifold and it looks like its an 1984. Would that have something to do with what was mentioned above about the manifold's bolt? Or would it have been common to put an 84 manifold on later cars?

    This is what I was talking about in my earlier post. It will not have the entire v.i.n. on the pad, but the numbers should match part of the v.i.n.

    Ford produced parts and implemented numbers for recognition. So the E4...1984...part number was utilized for several makes and/or year models.
