318 or 360 Roller Swap

I found some cheap roller regrinds online. That being said, I don't know if I want to spend the $ to swap a cam and springs. I might just degree what I have and invest in some gears. I want this build to be more pedestrian anyway. A smooth idle with good gears and a screaming TQ sounds ok to me.

be best to send out your factory cam to racer brown in MD and have him regrind it to fit your combo, and your intended use! by time you figure shipping and fleabay fee's probably be cheaper to!
