307 hp.
yes
You can put Oldsmobile 350 heads on an Oldsmobile 307, if the 307 is 1984 or older. It will take some work but it can be done, I know for a fact that it can, because my 307 has 350 heads on it. It runs great. I'm not sure about the cam though.
The A/T have about 287hp, and the M/T have about 307.
My Chilton book shows VIN ( Y and 9 engine codes ) - 8th " character " of VIN The 307 - 4 barrel carb - V8 engine is rated at 148 net horsepower at 3800 RPM and 250 ft/lbs of torque at 2400 RPM
Some do. What year?
The 307's were rated right around 200 horsepower (SAE Gross) with a 2bbl and single exhaust.
