I was orig gonna do dk blue block and leave the valve covers that light blue, but the green would look sick.
c/r? and yes it has E code heads which are pretty good flowing. i might leave them or send the to dave hunt i’ll decide after i pull it apart.
word, 455s of that year with 4bbl ranged 370-390 horse and 500ft/lbs tq from the factory :ohnoes
that buildup is sick! pontiac motors are a little different but the olds big blocks can hold their own too.
