There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

Do you (or anyone else) know the horsepower and torque specs on the 302 ?
I could be tempted...

Most of these engines were equipped with governors to limit output. I have some factory dyno prints from 196? that show somewhat higher numbers from a 302 with no accessories or muffler, and optimum spark advance: 168 HP at 3600 RPM and 275 ft/lb at 2400 RPM. The torque curve is virtually flat from 1200 RPM until it starts dropping off at about 2600. | | | | | Joined: Jan 2001 Posts: 687 Shop Shark | | Shop Shark Joined: Jan 2001 Posts: 687 | This ended up selling for over 500 dollars!
