Not Ranked
I have 6000 miles on my Roush 427R. Runs like a swiss watch. I was also torn between a BB and Roush. I drove 2 SPFs back to back. One had a Shelby all aluminum 427BB, the other had a 427R Roush SB. The heat from the BB was Huge compared to the SB. I live in Florida so heat was an issue. If you can, drive both and see how they compare in the North Carolina heat.
