jyardgirl according to my Chilton,s auto repair manual your 71 came with (2bbl carb) 245hp@4800 with torque of 350@2800 and 8.5:1cp. The 2 engines with (4bblcarb) came with 270hp@4800 with torque of 360@3200 with cp8.5:1 or with 330hp@5600 with torque of 360@4000 with cp9.0:1. I don,t know which engine your car came with but that,s the numbers they give for that year model 350.
