Time for an upgrade.

OH OK. Yeah id never heard it called a baffle before, my bad.

And yeah, Im not gonna do much to it, just all the aluminum stuff to get the weight down and preserve some handling, and a Mild Cam.

The 69 chrysler version of the 440 were rated at around 350 HP and and 480 lbs of torque. Id like to crack just a smidge over the line of 400/500.
that's entirely doable with steel heads if you don't wanna splash the cash for the alum. units.

that being said, modern alum heads, intake and a reasonable cam will do that number easy money.
