What pound are the new 3v engine injector size? An will 2v injector fit/work right?

 

The injectors are sized to give proper fuel flow for a horsepower rating. 3v engines make more horsepower than 2v's do. 3v's should flow more. 2v's are 19lb/hr I believe. I've been researching what injectors to use for 400 horsepower which is about 30lb/hr. They can be found in 2lb increments and claim better spray patterns.

 

the 3 valves use 24#ers i think
