You do loose "a little bit" with the 4BBL, but definitely not on the 408.
You can always install a "turtle" (cone on the center of the plenum) - they
help out with large plenums and low-end TQ. I'd honestly stick with the
4BBL as they are much easier to come by...plus, if you every decide to put a
blower on that engine, the 4BBL is the way to go.

Any suggestions on which M1 for a NA 408? 2bbl or 4bbl? The 4 bbl seems to
be about $200 cheaper but I'd get which ever has better performance. I've
heard that a 4bbl looses to much low end but that's not the case with a
408...
Thanks,
James
