    ok i looked at the one on the 305 in my blazer and then the one on my dads truck (which i know is a 350 for sure) and i couldt see much of a difference really. i was going to compare it to my truck to tell if it was really a 350 or if the PO was just BSing me..what difference am i looking for? /forums/images/graemlins/confused.gif

    They look the same, both fit and even share casting #. They are not interchangable because 305 balancer is lighter and has a hollowed out part not easily seen on assembled engine.

    Suffix code is going to be your best bet, as it will also tell you what vehicle it came out of, (if not original) performance, etc.

    There is a code stamped just under the passenger side cylinder head,a little "shelf"sticks out near the back of the altenator,its hard to see and most likely youll have to clean it with carb cleaner to read it--if your block was resurfaced it will have the code removed,in that case use the casting # on the drivers side rear of engine near the bellhousing,there are websites that have a listing of theese numbers,but I dont know the web adress--you can probably do search on "Google" and come up with it. /forums/images/graemlins/grin.gif
