These were recommended to me by wade as competition use Turbo grinds.

ES1214A

Inlet Duration
Total = 270 degrees
@0.050" = 214 degrees

Exhaust duration
Total = 270 degrees
@0.050 = 214 degrees

Valve lift = 0.520" (inlet and exhaust)

LSA = 115 degrees

Opening and closing events (Advertised)

Exhaust open 67 degrees Bbdc
close 23 degrees Atdc

Inlet open 20 degrees Btdc
close 70 degrees Abdc

overlap = 43 degrees

Opening and closing events (@0.050")
Exhaust open 44 degrees Bbdc

Inlet open 6 degrees Atdc
close 40 degrees Abdc

Overlap = -16 degrees

ES1543C

Inlet duration (advertised)
290 degrees
@0.050" 223 degrees

Exhaust Duration (advertised)
290 degrees

Valve lift = 0.546" (inlet and exhaust)

Opening and closing events (advertised)
Exhuast
Open = 74 degrees Bbdc
close = 36 degrees Atdc

Inlet
Open = 37 degrees Btdc
Close = 73 degrees Abdc

Overlap = 73 degrees

Opening and closing events (@0.050")
Exhaust

Inlet

Close = 38 degrees Abdc

Overlap = 7 degrees


Would either of them be any good for a street/strip or strip only cam? I have access to a stockpile of E series cams that I can get reground but I'd like to be close to the ballpark first time round instead piss f@rt around, especially since I still have to get the rest of my motor built.
