I recently finish porting my GT40p heads. The CFM # are 210 int. and 178 exh. I use the crower 15511(468/486 lift and 218/224 duration) and the guy at the speed shop where they put my heads on the flowbench told me that it was not a good idea to use this split duration cam because of the high intake/exhaust ratio of my heads. The cam mfg. recommend a 5800 rpm shift point( 6000 rpm with 1.7 roller rocker) and i think that it's a good match with my professional product intake ( edelbrock performer rpm clone). I need some explenation.
