BC Stage 3 Cam Card? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Does anybody have the cam card for Brian Crower's stage 3 camshafts? I'm trying to find the LCA and Overlap angles.

Or how about the LCA and Overlap angles for any camshaft that has any duration between 270-275. By overlap angle I mean amount of degrees the intake and exhaust overlap. I'm trying to find one that doesn't sacrifice as much at the lower end

[EDIT]
Thought I might as well ask: or a dyno chart for a NA KA block with 264s in there

Found JWT's 272 Cam Timing sheet just incase some people are interested:

The overlap degree is 35. According to the book I'm reading: 40 is a good spot for street cars

Still looking for BC's

BC was nice enough to email me the 264 and 272 timing. This is the 272:

Am I readfing this wrong or are there only 8 degrees of overlap?

Heres the 264:

Anybody know of any other 272 cams with under 35 degrees of overlap? And am I reading the BC 272 cam's right: they only have 8 degree of overlap?
