LS1 heads on SBF! Reply #30 – December 12, 2007, 10:38:01 AM If somebody is trying to do something like this then I doubt there considering "cheap". If they are there a fool.. Cheap would be aftermarket bolt on aluminum heads, or cheaper GT40p Heads. Custom grind cams are reasonable... The "blanks" I have seen for those have full round lobes to start with, meaning they can have any grind put on them. I'm sure those are done on a CNC cam grinder and the lift and duration are most likely plugged into a CAM program Like ESPRIT that I use (see below) I would think for a charge one could have any grind (including firing order) ground into any blank they wanted. "I want a Chevy grind on a Ford blank with X Lift and X duration" Sounds like an easy problem to overcome. Quote Selected
