Im thinking about running a bigger cam but not really sure. Im currently running a 224/224 .581/581 112 but I've upgraded to a circle d 4000 and 4.10 gears and bought a set of heads. I've been speced two different cams. The first is a 230/236 .612/.607 111+2, and the next is a 232/238 620/612 112+3. Which would be better and how much if a gain over the 224.

 

If you are wanting the most of it, go with the bigger of coarse. At the same time either of the two listed would get the most out of the heads and 4k stall.

 

Seems like your setup is ready for whichever! Differences between the two are slight, but your supporting mods wont make it hurt to get the bigger one
