[DeTomaso] Webers - update

[wkooiman at earthlink.net]

That's why I was surprised.  I have a Weber unfriendly camshaft - CompCams 294S.  It has a lot of overlap.  I don't remember the specs.  I have the cam card at home, and I can't look it up right now (at work).

All I can say is I have a driver friendly experience - so far.

Once I get the linkage worked out, I'll do more driving around to see if my first impression was correct.

Goran - I'll post some pics early next week.

I have the Webers specs at home too.  Like I said, though, everything is stock Weber 48IDA - except for 42mm chokes.  They are the brand new reissue Webers.  I believe they're made in Spain.
