Hot Rod 340 builds and dyno test.

I get what you're saying,
But in the Bulletin book, it is no where stated that these numbers were related to RWHP. And since the charts have been around since the 60s, I assumed they were flywheel. And since the numbers have, for me, always correlated to flywheel hp, that's what I assumed they had to be. Further,if those charts are RWHP, there would be no way to predict your mph using those charts,and using your engine dyno results, (unless you fudged the powertrain loss, with a pick-it-from-a-hat factor), so they would be kindof useless, for anyone wishing to hit a specific mark.
If you're right, then I've been wrong for a lotta years.
On the bright side my engine just gained about 75 hp.

Your right on that aj, all manufacturers engine ratings are at the flywheel. Why would a manufacturer publish rwhp? Doesnt make sense, they want the person buying it to hear the larger power number. You think chrysler would of sold a bunch if they said it only made 250 hp to the wheels lol no, when they say hp or torque they always give you engine flywheel specs because that is the largest number they can use to advertise
