Not Ranked
Ben,
The 2.25 Intake can be a detrament to intake flow if the chamber is not unshrouded enough!!!
Then, if you unshroud the chamber, you have to scallop the block depending on the bore size!!
Also, you have to keep a certain(not to be disclosed at this time) venturi ratio from port volume to port bowl depending on RPM range and usage of the motor.
In this venue, Cobra Kit cars mainly on the street, you would problably never reach an efficient ratio!!
So, in most cases, 90% of the time, the 2.19 intake is the best choice!!!
Tom.
