BlueGoat06

my best friend is buying a used 99 z28 M6, car has stock heads,stock intake, SLP lid, 3.73's, o/r pipe, flowtech LT headers, SLP LM1 and a 228/224 reverse split cam 228/224 .588/.581 112 lsa. he's still awaiting for delivery, in the meantime we were wondering how much horsepower and tq would it make. i looked through the forum, but i wasn't able to find such particular grind.

it looks like a mix between a 228r and tr 224

i ran a quick check with the VE Calc, and this is what i came up with

----------------------------------- 0.006 --- 0.050 --- 0.200
Intake Duration - ID --------------- 277 ---- 228 ----- 149
Exhaust Duration - ED -------------- 273 ---- 224 ----- 146
Lobe Center Angle - LCA ------------ 112 ---- 112 ----- 112
Intake Centerline - ICL -------------- 110 ---- 110 ----- 110

Intake Valve opens - IVO------------ 28.5 ---- 4 ------- -35.5
Intake Valve closes - IVC------------ 68.5 ---- 44 ------- 4.5
Exhaust Valve Opens - EVO --------- 70.5 ---- 46 ------- 7
Exhaust Valve Closes - EVC --------- 22.5 --- -2 ------- -41
Exhaust Centerline - ECL ------------ 114 -----114 ----- 114
Overlap----------------------------- 51 ------ 2 ------ -76.5

wonder how his hp/tq powerband would be. he wants to buy some heads, i told him i'll ask the cam experst around here.
