440. My car is mild and goes mid 11's on street tires and through the mufflers and I can drive it anywhere. The 408 offers sleeper status. The 440 offers wow status. In regards to being put back on the trailer by a SB anyone who has ever been to the track knows HP means nothing. A 4 cylinder pinto that run 25.0 could put you on the trailer. If you plan to run heads up you'd best forget about either of your engine choices. You need an 8 second plus car to be competitive in the heads up stuff.
