Most everyone is using similiar throttle bodies........750-1000 cfm
Most everyone is using the same or similiar header/exhaust combo, with minimal variation.....
Deductive reasoning suggests that if there is minimal variation between the parts, there should be minimal variation in the results!
The biggest differences I see in a HCI build that makes 300 whp vs. 360 whp is porting, exhaust setup, and camshaft profile. And to a lesser extent, who tuned it.
a 150 kit should make 450 whp all day long.
I did a bolt on 360 (stock longblock, kegger)....with a 150 wet shot and one of my FRP Nitrous Flashes it made 360/440.
Almost like you've done this before
