compression as one example,duration, overlap changes cranking compression,valve lash can change it.
compression works both ways like high spring pressure you have one cyl. compressing have another that just fired and is pushing another piston down. just like on valve springs people claim strong springs use power,but when you are opening one valve another is closing it evens it out. proof of that is turn engine with one valve adjusted it will be all you can do to turn engine each one you set engine gets easier to turn when all are set engine turns easy .
have you raced much this year? I got to go about 4 times set IHRA F/PS record at Mountain Park Pro Am 4th July weekend went 7.997. May go to UMTR race at Owingsville Ky. this weekend maybe Doorslammers at Ohio Valley.
Maybe give more info on what you've got going on might be able to help give me call if need to.

Another weird note is that 4 cyl DOHC motors can get awful high and still like it. I run 290 pounds. Got crazy when I found out tried to lower it and ran a lot slower.
Now I just accept it as one of those things I don't understand. Like how they get those ships in the bottles. LOL
