Wanted some input on degreeing camshafts. Im not sure which degree wheel to get to do this. I'm also not sure where my centerline is supposed to be(didnt get a spec sheet from Colt). Maybe some of the racer's can help me here.

Thanx,
Julian

are these the specs your looking for
Our most popular grinds for the 12V SOHC Honda's are known as the "TRI FLOW".
The principal behind the design is to open the intake valves progressively.
We find opening both valves at the same time causes more bottom end loss than necessary.
By opening one valve first allows the fuel to travel across the chamber at a greater velocity and then helps pull in the second charge.
These profiles also help cut down on overlap and work great in Turbo's and N.O.S.
applications.
STAGE 1 - PRIM INT 270° .384 LIFT
SEC INT 260° .384 LIFT
EX 274° .402 LIFT
Best all around wake up grind works with F.I. as well. No mods are required.
Power band is 2800 - 6500 R.P.M. approximately.

STAGE 2 - PRIM INT 280° .392 LIFT

Actually no those arent the specs im looking for. Im looking for the specs like intake/exaust centerline and such.

I've gone over some articles about degreeing a camshaft but still have one question. What exactly do you set the camshaft at after you determine the centerlines? I'm guessing this is where your specs come into play? Maybe someone can help me here.
