Hi. I have a 1977 chevy 305. fresh rebuild(7,500 miles), all stock with exception of a Comp XE262 cam and lifter kit, .500" lift valve srpings, and a holley 600cfm 4bbl carb. i was wondering what i could do to gain more low end torque with it. are the cam and carb to big for it? would going back to the stock 2bbl carb help low end any? any other suggestions for what i can do to gain low end? Thanks.
