Cam HP capability

Sorry, I ended up packing and totally forgot about the "run my program" deal.. Sorry Mal. I dont think 1.6s are a good idea with a profile designed to be fast with 1.5s, so if it was the XE282s I'd stay 1.5s. The older lobe M282S might benefit in both duration and rate of lift, and I'm sure the added lift would help. I think a single plane will make more peak, and it will tame the torque a little lower down which can be a help with these engines and small tires. I like the M1 single myself. If it was a 416 I'd runa 1" open spacer with it. On the 390, I think no spacer would be fine.
