    New to AD trucks and the forum and could use some help. Have recently purchased a '49 five window 3100 which has had the engine changed. Was told it was a 235 replacing a 216. Just trying to identify the current engine.

    Block casting # 3769716 , the head # is 3836848, the stamping on the flat by the distributor is FC 409J. The valve cover is held on by two nuts.

    Any information will be appreciated.:)

    Correct Head

    The head number is correct for a 235 but I can't find anything else for you sorry.:(

    Numbers

    I also found the block casting number from some listings at the old car manual project. Block 3769716 is listed as a 60-61 and the Head; 3836848 is used on 53-55 corvette 235 and another listing shows 53-62 passenger and all corvette.
    The engine code I can partially identify the F is for Plant (Flint) and the end "J" is an application code which is for a standard 235 Thriftmaster. If the C is really an "O" or "0" then that is a date code 04 (month= April) and 09 is (day=9th).
    The valve cover has probably been changed or they used the original 216 valve cover and used a valve cover adapter kit which is two studs to replace bolts in the rocker arm shaft and the nuts for the hold down on top.

    Hope this helps.
