Weber question

ERA Chas-

I spoke with Jim Inglese at great length about cam profiles with webers; he, of course, has a lot of experience with this. He feels that as long as LSA doesn't get narrower than 108 you should be fine, with 110 degrees being ideal for most engines. He also advised that staying away from split profile cams is probably best for most of us, but you can run a LOT of duration, just like Cal says.

Tim / 350,
Thank you also for the Inglese info. Everything you guys are telling me is pushing me towards spending a lot of $$$.
Thanks [?]

The only important duration measurement is the amount of overlap at .050. Inglese and Pierce asked me to keep the overlap @.050 below 28 degrees. My 294 Comp is exactly 28 degrees @.050. The valve lash from Comp was .020 hot. I opened this up to .028 and that will absorb some of the duration.(only on a mechanical cam of course)
A motor with compression will also absorb some duration, so take that into consideration.

The point to this: a large duration camshaft in a low compression motor will change things greatly.
