Cam & engine gurus gtf in her meow!

Trust me on this
the lunati or howard will wipe the isky chevy cm (the way Isky measures cams they (like MP) are longer seat to seat than they look compared to lunati, howard, comp and way way bigger than a similar advertised duration summit or crane or Elgin, Sealed Power, Mellings etc
If you have to advance a cam that much as suggested above it solves one problem- the dynamic compression but hurts the other side- fuel economy and exhaust heat- you are blowing efficiency out the tail pipe
get the right cam in the first place
