409? sexy beyond belief!! The stuff previously posted is true, I have a customer that has a 409 Impala. There are no provisions for bolting anything to the front of the heads like on a SB or a BB. The Impala that I work on has a Vintage air front runner on it. Here is a mouth watering web site for the not weak of heart to enjoy. To have a 409 in your PU would be cool, as long as you can sustain the cash flow. Never had much experience with these, but sexy cool.
