So I have a c5 and current have ls6 with an lg g5x3 112. I have a built lq4 6.1 and am going I be throwing a ysi on it. End goal is to make 1k through a 6 speed. Need some cam ideas. Heard the can I have may not be good for boost because of lobe separation. Been thinking about trying to find a 114 or try g5xb but I'm open to anything. I have a fast 92 and la2 Tb still have factory 243 heads but thinking about getting them ported.
