Which way do i go? I want to retard it 4 degrees.

Honestly, I am just experimenting. It was a running combination and I am just curious about what effect it will have. My hope is to soften the bottom end and raise the top RPM a couple hundred. If it doesn't workout I'll put it back. And then I'll know.
I have tons of 1st gear gear gearing. 28" tire, 2.70 1st gear in the trans and a 4.30 gear in the rear and a 3500 converter.
