Its a custom grind by Jones cam design,all I know about the lobes are they are the inverse radius.

I made 390/375 through my 4000 converter and 4.10 gears. Something sounds wrong to me.

The map pressure falling off indicates that there is an air restriction,so Im going to try to find out,if its the throttle body or maf or something else,I dont think its the intake..
