Re: 1974 Pontiac Superduty - Unrestored, 59,000 mi
 

My buddy's is a 1974 SD-455 Auto car. I believe he has all the original docs. I think HP in 73 was 310 and in 74 290 ?

Same engine both years with net hp rating.

Friend of mine has a 74 SD with a vinyl top. Dont know how many were produced, but certainly not many.

Same Engine?? Why the 20hp difference. Is that the year ( 74 ) that gross hp went to net. 1973 SD-455-310 HP 74-290HP
