well this is off the top of my head, but either 165 hp, or 150, 195 torque.
had 8.5:1 compression ratios where as the HO got 9 or 9.5:1 (dished pistons vs flat tops)
The lg4 got the smallest peanut cam, the ho got a lsightly better peanut cam.
if you wanna make your 305 run, best thing you an do is do an exhaust, a cam, and tune up that carb a little (the secondaries)
