307 pistons are 3.875" diameter. 305 pistons are 3.736". It might be possible to bore a 305 large enough to accept the 307 pistons, but the wrist pin location would be .230" off because of the different stroke. In short, no.
How much Hp from 307 bored 040 over with 305 heads roller rockers and 268 cam?
Estimating horsepower for a 307 cubic inch engine bored 0.040 over with 305 heads, roller rockers, and a 268 cam typically yields around 250 to 300 horsepower. The actual output can vary based on factors such as tuning, exhaust, and intake systems. The combination of the larger displacement, improved airflow from the 305 heads, and the performance camshaft can significantly enhance the engine's performance. For precise numbers, a dynamometer test would provide the most accurate measurement.
WHich motor is better 305 or 307?
There is basically no difference. 305 is a Chevy engine and the 307 is a Cadillac engine. They are both the same and assembled by same company Well, on the other hand, it depends on how you look at it. The 305 Chevy is a 265 stroked with a 350 crank. The 307 Chevy is a 283 stroked with a 327 crank. In theory, the 305 should produce it's best torque at a lower rpm than the 307. However, the 307 should be able to rev higher and produce a higher peak horsepower. Kinda depends on what you need it for. There is also a 307 produced by Oldsmobile that is a V8 engine. It shares no other commonalities with a small block Chevy.
