Brainstormin' 440 vs 5.9 ...

a little more food for thought: @Babyblue66 did a 440 that cranked out 420hp 480tq. granted a bump in compression to 9.6, the rest of the recipe follows with 906 heads that were breathed on a little with a bowl blend and 222/234 cam on a 112 that was sub .500 lift, topped up with a performer rpm, 750 and headers.

again, super straight forward combo of parts gives good results.
