Dyno numbers on my mill'd intake motor

I don't think anyone is questioning your #'s dude - everything adds up.

250 CI @ 18 PSI should make that kinda power.

If I recall he's up around 273 inches. His crankshaft has a 4.125 stroke.

I will say the cam I run and the single plane style intake makes it run crappy at low rpm's, at 10lbs boost the motor was piggy till 3300rpm, now that I'm running 18lbs it runs much better, the whole combo seems to come alive at 2700rpm and drives much better

Fast64,
Pull that cam out of there and you'll drop those 60' times way down!
We had that same cam and with the overlap it's just wouldn't get out of the hole at all. And just like you said, it would come on like gangbusters once the motor got wound up!
If you get the 60' into the 1.6 range then you'll be in the low 11's. Maybe high 10's.
You're almost ready to get kicked off the track anyway!
Good luck!
