318 small block
I have a 318 block that was out of an 89 w250 and I was gonna build it for my 390 stroker build but the block turned out to be bad. I'm searching for another 318 platform to build on. I was wondering what are the best 318 blocks that were made because I found out there was slight changes. Like what years had the best most durable block for the 318s?? Any information would be great. Thanks in advance

I read all newer than 1973-74 are 4 to 8 lbs lighter.
If your serious about the best 318 block find a nhra stock eliminator in O,P or Q with a 318 and I'm sure they'll know. other than that sonic test a few of them.

The 72/73 and possibly the 74 360 block can be bored to 340 bore size up to 40 over as it has the same core as a 340. But this change in 74 or 75.
