The 307 found in 1980-1984 GM models is a decent performer for its time. 1985 and newer GM redesigned the cylinder heads, instead of adding fuel injection to meet emission standards. Outside of a few Cadillacs and special editions like the Cutlass 442, the 307 was one of the only engines to actually lose power in the 1980s and become even more anemic. This while every other V8 in its class started to get a little power back (including the Chevy 305 and Ford 302).

Any true Olds enthusiast knows I am right... The 1985 and newer 307 V8 horsepower and torque figures are almost the same on paper, but the intake and exhaust ports are so tiny on the newer engine, that it simply cannot breathe above 3000 or so RPM. GM had the nerve to use this boat anchor in its full sized station wagons along with the Cadillac Brougham all the way to 1990, the largest passenger cars in the company. It was almost as bad as the Oldsmobile 350 diesel as far as acceleration.
