It's a comparison between this similarly built 367 vs 410, not this 367 vs W9 410 what comparison sense does that make?
I know, I used the W9 as an exaggeration, Same thing if you just put ported Edelbrocks with a 2.08 vs this 367 still not a fair comparison. Every time there's a 360 vs 400+ engine some always want the 400+ built better in some weird sense of fairness. Like I said makes no sense to me.
