Reply to "Anyone with IR injection run "naked""

On American V-8s with single 4v carbs the runner pattern is 4 long and 4 short.

This creates a split manifold where the short runner acts as high flow high rpm runner and the long ones, a low rpm high torque runner.

I would suspect that with the nature of a Can-Am car, that would more likely be the reason for the different lengths on the trumpets?
