That's a pre 77 block, can't tell ya anymore than that, what heads are on it? If it has #8's 73-76, 7A 72, 7's 71 (71&72, I could have these two backwards), 6's 70, 5's 68/69, (assuming it has its original heads). May narrow it down a little, not sure how to pinpoint an exact year. The number will be located next to the #1 and the #8 spark plug hole, you can't miss it.

According to 422.com it's 68-70 block. Which means that it would have num 5 heads if the engine has the original heads on it. Thanks for the links
Do you have the casting numbers for the heads as well? There should be a six-digit number on top of the middle exhaust ports, and as Oldsmoletick said, a number at the front of the head (if looking at the driver's side head). That will tell you which heads you have, rated chamber size, valve size, etc...
Check the passenger-side head as well.
Check the passenger-side head as well.
Head #'s should tell you the year, if they haven't been changed. The 68-76 used the same casting #'s.
well i bought the engine today it has heads that have 5 stamped next to the 8th cylinder...asuming it has the num 5 heads on it....still trying to figure out which year cuz i need a couple bolts and gaskets...does anyone no if engine manifold bolts are the same with the olds 307 and old 350 same with the head bolts and valve cover bolts all help is well appricated due to this is the first time for a engine swap...thanks
i need some help...i missing one of the head bolts and look at the price of them and i guess there over $100 for a whole set...where could i get just one bolt or will a head bolt off of a olds 307 work thanks
Most all the bolts are the same between the 307 and 350. However, if your 350 is a '76 or earlier block, then it has 7/16" head bolts. '77 and later Olds engines had 1/2" bolts.
is there anyplace were i could just get one bolt because its all i need?....motor seems to be 68-70 according to the cast numbers and i has #5 heads....excited to put in but got a few thing to take car of before it goes in
