headed for some dyno time soon and am hoping to be around 400 to the wheels. I don’t know the particulars of the dyno the my local shop uses, but that aside, what’s a fair estimate you guys think I should hit with the following mods:

2002 Z28
LS1/T56
BTR Stage 4 cam
241 heads have been ported and polished
LS6 intake
SLP lid and smooth bellow
1 7/8 longtubes
3” exhaust

its a 3.42 car with 295/35/18’s on the rear
