You are quite a bit short of 10:1. In any event, I'd use the 260H over the 268H.

Why? Cause of the duration difference?

The 260H, with shorter duration, will have better torque and responsiveness at take-off and low speed driving with a stock torque converter and hiway gearing. Comp Cams shows an RPM operating range of 1200-5200 rpm for the 260H and 1500-5500 rpm for the 268H, so the 260H brings on the bottom end at a lower rpm, basically right off of a fast idle speed.

I like the 260H, i had one on my 283 SB with 305 HO heads and a holley intake and that motor ran strong. But i am running camel hump heads and a stock intake, i just want a good cam to run with that.
