Thanks guys. Now why does the 65 have more than the newer ones? CR and cam?
That 170 horsepower back in 1965 was SAE Gross horsepower. And the 1990s 300 CID/4.9 liter EFI horsepower of 145/150 is SAE Net horsepower.
I don't own a 1965 300 CID--but that gross HP of 170 translates to about 135 SAE Net modern horsepower. Later--in the 1970s/1980s--that 300 six was making 115/120 SAE Net horsepower--with the one barrel carburetor and catalyic converter and EGR and other emission controls.

just piggy backing on this thread, I'm looking for the same thing for the 292 with a ford-o-matic trans H.P. and Torque 1964 f100.
Staying low for now

The 1963 292 V8 F100 engine was rated at 160 gross SAE horsepower. And the same engine was rated at 139 Net horsepower--per the rating plate on the inside of the glove box. I suspect that the old Net horsepower is the same or close to the new SAE NET horsepower.
