    id a 67 390

     



    Bought a 68 f100 and was told it was a rebuilt 390. C7 on the block tells me it is a 67 engine but not sure what it is or from because the 67 trucks didn't come with a 390 so if it is a 390, what is it from.

    Does it have the tag on the coil bolt. Ford motors had a tag on the coil bolt that told the year and size but unfortunatly most shade tree mechanics removed them when repairing them. The C7 casting number tells when the block was cast and if it was an early 68 it could have a block that was cast in 67 and it could have the original motor.

    Contrary to popular belief, you'll find that most your truck engines, espically the '68-72 and some '73s came mostly with the 360, be it the standard engine. Just about all of the '67's were 352's and a few were 390's. I think the 390 made the options list in '68 but was seen more widespread from '69 up especailly in the 3/4T and 1T trucks. tha only way to know FOR SURE which one you have is to ID the crank itself.

    Bore of 4.00 x 3.50 stroke will be a 352

    Bore of 4.05 x 3.50 stroke will be a 360

    Bore of 4.05 x 3.78 stroke will be a 390

    If they did a .030 overbore on the rebuild you can bump up those numbers to 4.03 and 4.08 respectively.

    I have seen 68 half tons with both 352's and 360's from the factory. I guess it depends if it's an early or late production for that year.

    The C-7 is for the first year that the Cast is used, not the year of build. (It is common for C6ME and C7ME 428 CJ blocks to be in 68 and 69 cars)Check under the oil filter spinner for the date code. This will tell when the engine was built. Your VIN code will tell you if it was originally a 390 Truck
