the six pack cam i installed was recommended to be installed at 115 center line. this was according to mr sixpack based on my gear ratio and tire height.




Sorry for the confusion, I don't know the specs of the Mr six pack cam (they are not disclosed, but if you have a cam it can be measured/profiled.) I was speculating that they may be close to stock, but with more agressive lobes?
Besides, I was just posting "computer simulation" results for comparison, and not having all the specific information avaliable, I had to make some assumptions on intake and exhaust port length, taper and volume. I used flow numbers from a decent flowing stock 906 head, and the 9.5:1 compression that was listed in the original post.
