The best stroker 408-416-426-435 combination in stock 68 340 block

I'd go 3.79 and stud the mains and heads to destress the block.
I don`t know much about small blocks, and have never owned one. I do know of a couple of Chrysler small blocks around here that I HAVE SEEN RUN 10:80`S , one is driven to the track and usually goes on the power tour and does pretty well. Both barracuda fastbacks.
