I knew I wanted a BB in my Cobra right off the bat. I was going to do the 460 route when I first got the car, but I was fortunate enough to have my engine builder find me a 427 block and iron tunnel port heads with an alum dual quad intake. I'm glad I went with this combo even though I'm sure we could have gotten a lot more power with modern aluminum heads/intake. This FE performs well, is very streetable, and sounds real good.
When I have the hood open, most people don't even know it's a tunnel port motor, but the keen eyes of some will note the difference and usually have a story about someone they knew that had one....one common trait is that they all seem to be smiling when telling me their story.
As far as the engine badge question I typically get asked at the gas station, I usually respond that it's a 427.....hmmmm, I guess that's a little white lie if you consider how the motor was stroked to 482 CI.
Tool Time George, as far as motors are concerned, to each his own but go with whatever makes
you happy whether it be a stroked SB or BB...just get it on the road and start enjoying it.
