Dang. I didnt see this thread till it was to late. ThunderBolt beat me to it.
I have no doubt that the Net Flywheel Horse power is as claimed by Ford in the 60's.
As Thunderbolt mentioned though, the ways Horsepower is rated now is diffrent. Back then it was rated with no nothing, no Powersteering, no Waterpump, No Fan, no AC.
Something else to think about is, how much of a drag those old Power Steering pumps and AC compressors put out. Todays stuff is alot more effiecint and doesnt take as much power to turn.
I think 120-130 RWHP sounds about right for a loaded C-Code 289, thats with an auto, and power steering.
I wonder what my ol' 289 turns out. Its got some balls to it. And in that light car it screams along pretty good.
