I don't think they changed only 5.3 heads and 5.7 heads. heres the flow number before and after porting:
Intake
lift Before After Gain
100 65 74 9
200 129 161 32
300 191 229 38
400 223 261 38
500 231 294 63
600 229 306 77
700 227 310 83
Exhaust
100 53 61 8
200 101 115 14
300 135 163 28
400 165 191 26
500 179 212 33
600 185 225 40
700 187 232 45

 

Are those numbers @ 28" H20?

Also, does anyone have cam specs for a stock LS1?

I am putting all this into Desktop Dyno 2000 and getting crap for results. I put 200/200 .500/.500 for the cam. What is the Lobe Center Angle and Intake Centerline? I am trying to make a stock LS1 in this program.

The LSA on a stock cam is like 116.5. anf yes its test @28 on a superflow bench at 84 degrees. And I think the cam specs are more like .490 on the intake and exhaust
