The stock advertised compression ratio is 8.5 to 1. The smaller chambers should raise it about a full point. This should result in just under a 8.0 to 1 dynamic compression ratio.
He was looking at that cam since the lift is higher and it has more duration at .050 when compared to the stock 340 cam. The HS roller rockers are 1.6 ratio also.
His goal is to add some snap and low end torque since the car is equipped with the stock 727 and 3.21 gears.
I recommended the smaller valves to him since that combo should have some nice high velocity ports when combined with the aggressive cam ramps. I think he likes the sound of being able to say "it has 2.02 valves" though.
