100 cfm more with anular and downleg boosters can't beat AFR
However there are two changes that likely affected the combustion.
One is that the engine had 340 cast iron exhaust manifolds, but since 2016 has custom headers.
The other is a change in timing curve.
No skirts onthe downlegs
LOL. Basically Yes same hardware but tweaking the carb. That dyno session where I tried three different springs along was pretty helpful. I'll dig up the missing screenshots if I can.
