Ok now, pay attention folks... I found my camshaft spreadsheet...
The 71-74 360 2 bbl cam had 252/256 duration and .410/.412 lift...
In 75 they switched to 252/252 duration and .410/.410 lift....
Here's the difference according to Desktop Dyno 5 with a 318 and 9.0 compression:
71-74 360 cam:
View attachment 1715799366
75 360 cam:
View attachment 1715799367
The 75 cam has 1 more horsepower and 3-4 more torque up to 3500 RPM then the 71-74 cam has 2 more horsepower and 3 more torque above 4000 RPM....
