I see a lot of specs of crap on the back side of those rod bearings that would have effected the local clearance, and the bearings look like they where wrongly assembled with oil on there back side.

The detail I am looking for in those rod cap and big end photos is the impression from the numbers and lettering on the back side of the bearings.

If that impression is not clearly readable in the cap or the big end, then the bearing was moving, which is not good!

The only reason to not go with a stroker other gas usage is your stock heads.
If you’d making more then enough torque you will only havd more , and if you don’t then also add a bigger Cam then your HP peak will be attained at a even lower rpm then before.

Stock iron heads used on a street type motor of 455 cid or larger are done to the point of sticking a fork in it by 5200 rpm.
