Straight up or exhaust bias? Considering either a 216/220 or 212/218 or 220/220
When using stock head/displacement LS1 with long tubes, cats and true duals(GTOs have more undercarriage room for tubing) how do you select?
Found a number of lobe catalogs with what I was looking for.

Actually.... the question should be "what are you trying to do?"
The aggressiveness of the lobe will have a ton to do with the RPM range you are running it.
In reality what you are looking for here is the area at the valve.... which could be easliy solved with a rocker arm change on a exsisting cam lobe.
