I have tested SGC Stg II's In & Ex replaced exhaust with a .224 .420 picked up 25RWHP,i'm starting to think we don't need more then .225-+ exhaust cam.

I have in my notes, from an old LPE catalog, that they also made a larger cam. 244 or 246 duration @ .050, and .454" lift. Anybody else heard of those? I've long since thrown the catalog away.

Aaron gaved me some time ago the following specs about his cams.

Stage 1 .230 .230 .420 .420
Stage 2 .236 .236 .440 .440
Stage 3 .242 .242 .454 .454

I post in the next weeks a dyno sheet about my customers 427 with stage 3 cams.

Hi Sam,

I wonder if my data is wrong or if he may have modified the grind a bit.

Looking forward to the 427 results!!

I measured the Stage II's from what i remember they are .237 no big deal for 1 or 2 degrees.
Most tuners will say 1 or 2 degrees difference just so they are different from there competitors cam grind.
It could be same cam and same manufacturer most customers don't check/measure cams.

True story. I measure every single cam(s) I install. Sometime the numbers can be surprising, right along the lines as what Pete mention's.
