440-1 flow numbers

I 'only' am using the 2.25" and think it would make over 1000 with a couple of tweaks but, yes the 2.30' would show MINOR improvement. I'm using the TR 2x4 but, I feel if it's on a RB block and the 3x single is used it'd make more power. A custom intake 'done right' would be above that. I'm not sure at what point the head gets critically thin where it'll crack. My heads aren't done to that level FWIW.


Thanks for sharing Sean. You’ll have to keep us informed of the direction you go. Either way, it’s gonna be cool to see how fast it goes.
