-> CH> That sounds very much like the "too much cam" syndrome.

->The cam is a copy of the old L79 cam, other than what looks like a bit too
->much duration (222{at}.050 or 290 advertised), the lift is a paltry .447"

The trend these days is more to shorter duration and higher lift, with
a computer-designed constant accelleration parabolic curve.

->The cam in my Nova is a crane fireball 290H. Similar specs, except with a li
->of .454", and essentially an identical engine, very different
characteristic
->when you punch the gas. Sure, theres an extra 1000 pounds on the truck.

I found a very interesting Crower cam for that '66 366 big block Chevy
being built.  Almost an extreme of the short duration/high lift scheme.

->The only cross to my mystery 1137 AI cam I could find, is a blueracer
->WG1137 grind. You can see the specs if you goto the crane cams web site and
->click on the blueracer link.  454" lift, tighter lobes, and less duration.

I haven't found anything more, either.  You'd think that a cam by a major
manufacturer like Wolverine would have a site..

-> CH> 
-> CH> Yes, there is an adapter, now that I think about it.  Used early on
-> CH> before they had the proper BBC TBI manifold.

->Good. Couple it with an Edelbrock performer rpm manifold, could make for
->an interesting experience.

Yes.  It would likewise be useable even adapted to a smaller manifold like
the regular Performer.  Those are up on eBay all the time for $50US.

-> CH> I saw that on the news.  Yikes!  -40 is cold..

->Truck started right up the following morning. The winds
->have been COLD recently. Hopefully next week sees us finally staying above
->the freezing point. I've had enough with winter.

Cold here, too.  It does look like the cold siege is over for now.  Next
week looks much milder.  Maybe we'll have a great summer.  That often
follows a brutal winter, for some reason.
