Piggy back question to my timing a 360

Awesome, Thank you guys for the explanation. Im not totally sure how to gauge the springs and weights, and since I wanted to know the HP of this engine anyways. I think Im going to bring it to the local dyno shop to have them fine tune the timing, and carb. Its running really rich and I believe its the metering rods. I'll let them tweak it all and get this thing running perfectly.
