    I bought a 64 gmc truck because i love older style trucks but the engine is an inline 6 but the inside of the truck on the driver side there is a metal tag from GMC that says it is a 305E and so much torque and rpm, but i cant find existence of a 305E inline six? was the motor swapped or is this not a 64? any info would be helpful because this thing is getting expensive and i sont even know exactly what it is, thanks.

    Sounds like the engine was swapped. The 305 was a v6, it was big and heavy, lacked power and drank a lot of gas. It's proper use would have been as a boat anchor...Big Tim:cool:

    I do not think gmc offered a inline 6 in 64, the first 250 6 Inline was in 66


    here is a link to Jollys gmc website it has lots of info:

    Earlier GMC inline six cylinder engines had the engine serial number stamped as shown here:
    http://chevy.oldcarmanualproject.com/gmc/5559mm/5559mm0i05.html
    The first three digits of these older engines serial numbers were the size of the engine such as 302, 270, etc. There could be an alphabetic prefix (A through G) that signified slight over sized pistons and/or undercut main or rod journals on the crank from the factory.

    We have the single-barrel carburetor you are seeking, that was factory-correct on the 305 V6. It is a Stromberg.

    Also, the '60-'66 GMC trucks were equipped with straigh sixes or a generation of the 305...A, B, C, D or E.
