Stock 340 dyno tests?

I know what a non-stock 340 can do. So what.

I watched the dyno needle go over 600 horsepower with Dad's T/A blocked 357ci/340 back in the NASCAR 1970's. But it sure wasn't factory stock as Cale Yarborough couldn't pass it on the back straight at Riverside.

I've seen one person reference a factory stock 340 dyno test. <300 HP.

Some reference rebuilt/blueprinted 340 engines........but........so far........

Nothing factual matches the wild imagination of massive factory stock 340 horsepower.

I think. I wish. My butt dyno says......... Drummer Dinwiddie told me that his......... My neighbor Mr. Swartzenickle had one that......... An old engineer said.....
