Let's Build a 416 with Cast Iron Heads and Manifolds
Ok I'm just gonna point out this seems like someone's tugg of war with direction.
"Bigger is better right"
Just stroke a BB to 540 or so and top it off with a nice set of 516 heads.
I remember a few threads where BrianT was being a real true colors kinda guy.
Enjoy the build n best of luck.
