The cam should be fine, but Like Rich said, I would have expect atleast 12 degrees split between int/exh.

I asked about that too, he said the shorter split had to do with my full exhaust system. He said the lsa would be tighter than 114 if I had no I/C, to help cool the piston with fuel.
Now, I'm not saying he's right, but they know more than me. I'm sure I screwed up his explainations too, so take them for what their worth.
This is going to be interesting in any event, I will be sure and keep you guys posted.
This will take awhile to get going though, my wife and I had a baby 3 weeks ago today, and I live in Wisconsin (cold and snowy).
Thanks for all the replies, and Merry X-Mas, all.

I did a cam with cam motion. 231/ 240 - .538/ .560 114* lsa (rpm 3500 to 6800). App is... 97ss M6 383 - D1/ 72# Seimen Inj with LT1_edit v2.2 obd2 flash. I did my own programming and had to get a wideband O2 to tune it. The O2 WB-Dynojet worked for me, but, the gm pcm obd2 running a MAF in closed loop control is @ the max with this cam (about 8* overlap @ 0.050"). I finally got it running good, but, had to re_cal the MAF for closed loop operation. I like a wide lsa for the street. I would not go any larger than 114 lsa for a street car. Now, happy with the CamMotion cam. B.

I have a stand alone efi system with speed density, so MAF is no concern. I just hope this setup is a handful (he he).
