If I had to guess, I would say that it was pretty close to the specs of the 305 in the 84 Camaro: HP- 150@4000 Torque- 240@2400 - Freed
I couldn't ifnd the info! All I could find was that depending on the factory heads, you could gain ~10 ft/lbs
I PM-ed ABben32 a few minutes after his question with the figures, but although he read the message, no reply from him o No: It's 240 lb-ft @ 1600 rpm and 140 hp @ 3600 rpm for the 307 Olds.
