No need for the pictures, I had to return Comp Cams a custom ground steel billet solid street Hemi roller cam with EFI back due to them shipping me a odd ball core with six cam bolt holes on the front
They tried to get me to use it after they checked it on their cam Dr. NO WAY I'm installing anything like that in a customers motor
I ended up having Tim Banning at FHO send me one of his special EFI grind solid roller cams from Comp, it was correct for the motor
