If the world and planets lined up…..
I wouldn’t worry about it. While another 1/2 point is what I’d shoot for, it’s not the end all. You could…. Just sayin… move the cam around and close the intake valve earlier.
If you don’t have the cam yet, I’d contact Bullet or Schneider cams and discuss it with them. FWIW, it’ll help to have your cylinder head flow numbers handy when you talk about this.
If you have the cam, just stab it and rock it, it’ll be fine @ 10-1.
Just what exactly is 240-ish?
