Horsepower Estimate?

If Jim's thread doesn't support this 340 making more than 300hp if everything was in decent shape, not sure what would convince folks.

@PRH
Had a 360 with a 214/224 cam. Car ran high 11's at 3000# Sounded like grandmas 318 Duster.
Nothing will convince people to change their minds, if they aren't open to receiving, evaluating, and acknowledging new information.

Some people are just stuck in their ways and perceive everything that doesn't 100% agree with them as some kind of personal attack. They just go into fight mode and choose ignorance over enlightenment.
