    oh and i wouldnt trust a minimum wage employee at an auto parts store to know much about a car that is older than they are. chances are they have never driven a carberated car. there are some knowlagable people at auto parts stores but not many.

    listen the motor says 3.3 or 3.2(going to scan the engine now) liter AND as you can see its a INLINE 6. its a very rare motor thats been extremly well upkept. By the previous owners. Runs as strong as a ox. Looking online it appears that its had a 302 upgrade. 50 bucks 6 pack and burgers hotdogs for anyone who wants to come diagnose it soon.

    after inspection the engine says. 5.136 .L on the engine, straight inline 6. marked on the front left side of the head.

    is that the engine size/spec?

    not being funny or anything but wth engine do I have! if its not a 250 or a 302 inline 6. If anyone needs specific pictures to identify. Also know it was before power steering and has none. If that helps.

    The thread has gone insain. If the starter is low where you need to go under the car to replace it, its a 250, the starter will have 2 bolts. If the starter is high and you can reach all 3 bolts its a 200.


    This is a 302

    If you got a 302 starter and the motor is a 250, it should have hooked up:tiphat:

    most likely this is not the orignal motor for the car. it has been replaces. that means it can be anything. it could be stroked to 302 cubes. im sure that the people at www.fordsix.com can help alot beter than we have been able to at this point. i do want to know what the verdict is once it is figured out.

    To clairify what happened, i quoted chris's post because i thought it was funny, not yours. Your being miss lead and i thought this tread would have ended along time ago. The hose comming off of the valve cover (thing that says powered by ford on it) is a pcv hose. It goes to the base of the carborator. good luck!

    I think you may be confusing Liters and Cubic Inches. If on the engine it says 3.3L then that is 3.3 Liters not 303 Cubic Inches. In 1970 your Maverick was able with a 3.3L engine, that means it is 200 ci (cubic Inches). The 250 ci engine was also available that year which the guy at Autozone tried to sell you the first time but it didn't fit, because your engine is a 200 ci (which is the same as 3.3 L).

    Anyways, the hose coming off the valve cover is for the pcv valve. It goes to the lower port circled on your picture of the carburetor base. I am not sure what the other port is for, maybe it is the one that goes to the ported vacumm switch and then it sends another hose from the ported cavumm switch to the distributor. Look in your books or online for vacuum diagram of the prted vacuum switch.

    ok well thanks a bunch, I am also at a loss at to what it is. :D, thanks ryan that makes sense. but I looked for the 3.3 that i remember seeing It must be covered in dirt but it did say 5.136.L just like that on the front in a circle.

    all good justin no big deal.

    Here's a picture of a 200 or 250 straight six, can't tell from the pic

    before.jpg

    If your car has the white sticker like the one you see towards the back of the valve cover then it may say on that sticker what size your engine is. I believe it usually says it in cubic inches and liters, example, "200ci 3.3L"

    This engine has the pcv valve in the front hole of the valve cover, your picture has the pcv valve in the back hole. This may be a difference between the 250 and the 200 motors or just a difference in the year of the car, not exactly sure.

    Here is another picture form a 1970 Maverick, It has the pcv valve in the back of the valve coer like your car, notice the hose is going to the bottom of the front of the carb, towards one of the ports you had circled on your picture

    From what I have seen looking through the Gallery at the pictures that say what size the engines are is that the 250 engines have the pcv valve in the front of the valve cover and the 170 and 200 engines have the pcv valve in the back hole of the valve cover.

    Was it possible this was a Ford 300 straight six? Would require some significant mods to wedge in there but it has been done as verified on the fordsix.com forum. Since TheKingofDemons says it runs strong it wouldn't surprise me a bit if that's what he's dealing with since most of the 200 and 250's can't make that claim.

    Hey, my 200 runs strong. Well, if we're comparing it to a Geo Metro with a bad cylinder...:burnout:
