About that time 470,500, or 512

The cost of the stroker kit is the same but the supporting parts have differnt costs. Going through the same thing with my RB build. Same price for a 500 or a 523 kit. I'm leaning on a 512 kit as it sounds like A LOT more work to get 523 oiled and needs some major heads and carb to run oh and streetablity because a concern.
