I have been playing around with static and dynamic compression ration calculators to try and make sure I get my engine build right.
According to CompCams, they grind a 4 degree advance into their cams, but that would put my DCR a bit too high (around 8.3). I've found that by retarding the cam some and installing it only 2 degrees advanced, the DCR settles back to a more livable 8.1.
I see a bunch of timing chain sets on the major supplier sites which have the ability to install at dead-on (which would be 4 advanced with the comp cam I think), or 4 degrees advanced or retarded. Those sets are relatively cheap and common. If you look at them on the Summit site, they state max crank advance at 4 degrees and max cam advance at 2 degrees. Descriptions only state being adjustable in the above increments.
If you can adjust either the cam or the crank offset, shouldn't it be possible to use one of these sets an get the 2 degrees I need?
What am I missing here? Any help is appreciatted.
