    Does anyone know how to "trace" an engine. I was told you could find out a lot by using the numbers that are on this tag, but I'm not sure where to look?


    Thanks!

    Those tag numbers are for a dealer or other source to use when ordering parts.
    For instance a CA. car may use a specific part where a PA. car may not use the same part number for the same model because of emmision calibration differences.
    It's not really an engine ID tag.
    Engine ID on the Mav/Comet is on the block it'self.
    Later into the 70s with emmisions coming more complex, tags on the valve covers told a lot if speific info on what calibraton the engine had in stock form.

    I can tell ya it's a 1986 engine. Is this a H.O.? I read somewhere '86 H.O.'s had funky heads on them that weren't very good. Could have been '85 though, can't remember.

    ha.

    I tried to get some info from a dealer on one of those on an 80 something motor. Gave me something to laugh at anyway. Dealerships are useless.:rofl2:

    The E6 is obviously 1986 and the number above it is the calibration code that I believe is related to emissions requirements. Don't know what the top one means. Jamie, the 86s had more restrictive heads, intakes and throttle bodies.

    Yep, Rick told me it was an '86 engine. No, it's not an HO, but it's a EFI 5.0 engine. Back when I built my original engine in my Maverick, it had a Windsor 302 in it, so part of the build up was putting Windsor 351 heads on it so it could "breath" more. However, I don't even know if that applies to these newer engines? Is there still differences in Windsor versus Cleveland's, or is all that mute now? Would there be 351 heads that would bolt onto this engine? If and when I get into "phase 2" of this Maverick restoration and start playing with this engine, I think I'll take it back down to a carbureted system, if that's possible. Seems like keeping all the computer crap working on an EFI engine swap would be a lot of headaches. My main objective is to find out as much about this engine as I can so I know what the heck I'm working with.

    Thanks for any help you can offer!

    Art, I would just treat it as any other 302. I think it would most definately benefit from a head swap and converting back to carb since it's an '86. Main thing to remember if you put this engine in your Maverick is that the balance is diffrent from the engine currently in there.

    Jamie,

    What do you mean by the "balance"? I know I currently have a 250-6, and the 302 is heavier, so suspension changes will need to be made if I want the same stance (however, I did hear once that the springs in the larger 250-6 and 302 V8 were the same?), but I'm not sure what you mean by balance?

    Ohh sorry, I didn't realize your car had a 250. I was talking about if it was an original 302 car, the balance of the 302's changed from 28oz to like 50 oz in the early 80's. So you couldn't just bolt it in place of an original 302 without changeing some stuff.

    Ok, got it. Yeah, this will be a straight 6 to V8 swap... someday in the future! I just want to get some idea of "what do I have" with this EFI engine I have sitting in my shed so I know what I'm up against.

    Art, the non HO motors have smaller throttle bodies and intakes. Also, the non HO has a different firing order and the computer is programmed differently. Finally, the cam is different as well. In some cases, the injectors are not even 19lbers! This engine is likely out of a large mercury or ford. I would basically pitch everything except the short block. Change the cam, install better heads, a good intake and carb with decent headers and you will be on your way. Remeber, there was an old carcraft article where they used a stock 5.0 short block with AFR 165s and 1.7 rockers. I think the headers were open and I can't remember the intake and carb. HP was about 400!!
