Lift at TDC

Jonathan H

Recommended Posts

I am about to fit verniers to my K series S/S, but before doing so I thought I'd see what the cams are set at with standard pulleys.

The first reading I get on the inlet is .023".

  Are they usually this far out considering .060" is recommended or am I doing something wrong?

I generally measure before fitting verniers. I have had figures as low as 5 thou, Julian's was around 17 thou. It is rare for them to be more than 30 thou, the exhaust cam is usually much higher. Lift per degree is around 3.5 thou so it indicates that your inlet cam is around 11 degrees retarded.
