Off the KC build sheet: Item#: 35-426-8 Comp Cam.
Cam specs: 555/576 288/294 236/242 @ /.050
These cam specs got me curious.

My 392" stroke RDI w/Comp Cam dual-pattern hydraulic roller specs at
.540/.540 lift, 240/246 dur @.050, 110 lobe centers. Compression is 9.7:1 with Victor Jr. heads.

I was always under the impression that I had too much cam for Webers. Mine has 4 degrees more duration (i.e. more overlap, which Webers don't like a lot of), but measurably less lift (.015/.036).

Any thoughts on this from the gurus? I'm not in the market for a different induction set-up...just trying to get educated at the moment.

Thanks,
