David Vizard bench flows a BBD 2bbl
Thats right folks an Ovalport 440 head for the masses...
Much thicker flanges with the extra cooling passages for the spark-plus cooling, not seen again till 1978-79.
Shame the 'powers to be' liked the rectangle port 906's so much...
You don't 426-440 wedge pistons like this anymore lol...
Destroked 426-440 crankshaft with 4.320 bore pistons.
Much better breathing than the smaller 4.250, 426ci bores.
