P to V question on a turbo ls1 These are the specs on my turbo cam.
Intake & Exhaust
Lobe Seperation = 114.9
valve overlap = -10.8
Intake
valve open = -.8
centerline = 110.9
valve close = 43.3
Valve lift = .57526
Duration = 222.5
lobe area = 26.35
Exhaust
valve open = 48.5
centerline = 118.9
valve close = -10.1
duration = 218.4
Lift = .56575
lobe area = 25.32
TEA is building me a set of heads with 70 CC chambers and 2.05 intake valves and larger exhust valve (can't remember on the exhust side)
I also have Coated Diamon -8.6 blower pistons and the required 6.125 connecting rods for these pistons
Am I going to have Piston to valve clearance issures? I was planning on claying to double check I was just wondering if anyone knew off hand..
Thanks, Dave.
