Hello all. I am looking to make some upgrades to cam/lifters/springs in my 350 sbc. The engine is currently in my 66 impala 2 door hardtop. It has a 700r4 trans and 3.08 rear axle ratio (I have a 3.73 ring+pinion that i am planning on installing ). The engine is mainly stock, RPM airgap intake, long tube headers, and 600 edelbrock performer. The car is only street driven, and my daily driver in the summer months as its not suitable for the cold months here in Canada. What Im looking to do is get some more horsepower without spending a ton of money on bottom end or new heads. I would like to change the cam to get some more lift and duration and of course put in the appropriate lifters/ springs. Any opinions are appreciated. thanks.
