opinions welcome on build.

I’ll take the cubes.

427” with j heads, dual plane intake, ex manifolds........

Peak Hp varies by 5 numbers from 5600-6300.

Same top end and block at 402”..... peak hp varies by 4 numbers, within the same 5600-6300 range.

32hp more from the bigger motor, no loss of usable rpm....... with heads/intake/ex that are way too small for either combo.

Picked up 34tq too.
