Re: hp ? on a stock 350
255 gross, and I think 200 net. Those engines were 9.0 to 1 compression if I remember correctly and the cam wasnt engineered with emission's in mind.

175 is the '72 factory net hp rating for the 4bbl truck 350. '69 - '71 were factory rated at 255 gross hp. Note that there is no difference between these motors.

Re: hp ? on a stock 350
'69 - '71 were all rated at 255 gross hp. AFAIK, all were 8.5:1 compression. I am talking about 4bbl 350 cid light truck engines.

Re: hp ? on a stock 350
maybe it had something to do with the new emissions laws at the time? new emissions equip dropped/changed hp ratings, perhaps...?

Re: hp ? on a stock 350
