414 Dyno results: Missed combo?

I think the "lack of power" is sort of a slight combination of things. I think it's funny it's considered less than stellar results given you got over 100% VE. Which is considerable in itself.

The carb is a hair on the small side.
The cam is a hair on the small side.
The headers are a hair on the small side.
1.6 rockers would be nice.
Over 100 VE is great. Curious what your dynamic compression ends up being.

With you mentioning sub 500 lift cam. And your current power placement. I'm going to guess the cam is FTH in the 220 duration area? I would be curious to see a pull to say 6k rpm. I know it won't make more power. Given where the max torque is. But I would be curious to see what the powerband does.

What ignition setup are you running?

In either case. That's a buttload of torque and down low. That thing would be very hard to control on street! Curious to see what cam is in there.
