    uahhh? ummm? Duh? what\'s the difference between...

    I must be a real dumbass for asking this question...
    But I believe my truck has a replacement engine in it.. I just got it recently and the stock numbers don't match up.

    So ..I'm trying to find out if it's the original stock 305 engine or its a 350 replacement? Whats the significant differences and how can I tell?

    I'm really, really really sorry for asking this-- but I think it'lll amke the differnce when I go for top and bottom engine parts...

    (it looks like a 305 to me but the valve covers are not stock and the oil pan isn't stock either)

    -all comments insults greatly appreciated, i think? d'oh!

    This isn't a dumb question. It gets asked often. Get the casting # off the block. The # should be on front of the block close to where it meets the head. After you get the # go to http://www.mortec.com and this should tell what you really have.

    I don't believe there are any visual external differences between a 305 and 350, i think it's all internal
