I do remember that now. I remember thinking when you posted that, I’d like to know the whole combination; compression, cu/in, carb size (750hp), and how much power it makes. I think at this point we all can agree that none of this stuff is set in stone or intuitive. Testing, testing, testing, is the ONLY way to know what will work on a specific combo. I’m looking for a quote from Tuner I posted here somewhere from RFS and it explained the relationship well and how all the variables interact. Be back shortly
