What rpm are your shift points at (A4) or where do you shift (M6)? I’m looking at one of these two cams to use with stock heads and just MACs + the common bolt-ons and I’m wondering where you guys are shifting. I know I should go based on a dyno chart, but I’ll just like to get a good idea of where everyone else is at.

 

A4 with stage I style heads with Cranes and Vig 2800+Mac/ORP/Borla.6400 rpm (5900-6000 with NOS)
212-218 Cam

 

M6 with stage 2 heads 216/220 I shift at 5800 - 6000.

 

Thanks guys. <img src="images/icons/smile.gif" border="0"> Keep 'em coming!

 

216/220, A4 SY3500 3:73 gears only shifts at 6000 each time I have some fine tuning to do as soon as someone in my area becomes LS1 Edit knowledgeable!!!! *COUghFIREBALLcOUgH*

 

My shift light is set at 6500 (I have a custom ECM program by Ed Wright). My star stage 2 bites hard at that rpm and my 4:10 seem to like it too!

Wow, sounds like you guys shift pretty high! I thought with these cams and their relatively low lift numbers that a shift in the 6200 to 6300 rpm range would be good. What about if you had stock heads? Would 6200 be good, or should I try 6300+?
