mid 70 302?
i just aquired a used 302 out of a mid 70 modle granada, my question is, is the mid 70 modle block stronger than the 86 5.0 block I have, and would it be better for my street/strip 347 stocker motor. The motor looks to be in good shape and got regular oil changes. I not sure if the bore is oversized yet.

Besides the boss 302 blk, out of all production type 5.0 blocks I would use the one you have

interesting. I was told the opposite earlier this year. Either way, if you are planning to use a roller cam like the late models, you will be spending around $500 to make one work

Re: mid 70 302?
the early model 302s like late 60s and early 70s are stronger than the 90models or 80s. I would rate the Boss 302, then mex,302, then the early model 302s as the good prod. type blks

Re: mid 70 302?
As Lee pointed out, if you are planning on running a hydralic roller cam you'll need to do a retro-fit to that block, or use cross bar style lifters.

Re: mid 70 302?
You're better off keeping the stock roller block and using your $500 for a good balance job etc... and still be able to make 400-500 hp. The old block you have is only marginally stronger and not worth the conversion. I know some guys turbo'ing the heck out of 347 stock-block motors. One just went 10.3's @ 134.
