well if you got a 1970 350 4 bbl the w-31 engine it would be 325 hp 360 ft lbs torque. Any thing after this just gradually goes down in power.

1971 - 260hp 4 bbl 240hp 2 bbl
Beginning in 1972 all power ratings were measured at the rear of the transmission with all power accessories installed and running, therefore the power rating is representative rather than exact.

all 350's from 71 and up were 8.5:1 comp.and in 78-80 were either 8 or 8.5

why olds didnt up the compression on the 403's and put them in more cars is stupid. What a great engine it could have been to come factory in the g-bodies!!! Put a great set of heads on it, about 9-10 comp. dual exhaust headers and decent cam, roller valvetrain, Imagine the numbers then????

That was the W-31. The 350-4bbl that was standard in Supremes was rated 310 hp and 390 ft-lbs torque.

Three 350ci motors for 1970, all called Rockets, as are all Oldsmobile V8's. The standard 350 2bl is rated at 250hp, the 4bbl is rated at 310hp, and the highperformance W31 is rated at 325hp. The W31 would have big valve #6 heads, and aluminum intake marked Olds 350, special carb, and big harmonic balancer. The other 2 motors use the #6 heads as well, but with smaller valves, and lower compression ratios. The W31 used a flat top piston, the other 2 used dished pistons of different depth
