[Roadsters] Cams

[Keith0alan at aol.com]

Actually the B cam with SU carbs is a nice setup. Most of the HP gain going 
 fro A cam with SUs to the B cam with Solex carbs is in the cam not the 
carbs.  The solex carbs give you a lot more misadjustability and a little more 
power.  Unless you need the ability to tune the carbs for the track 
condition that day I  would recommend the SU carbs and a B cam. The B cam does have 
a little rougher  idle but not bad.

The "B"  cam was designed to work with the dual Solex intake setup and
produces max  power at higher revs than the standard cam. Frankly I doubt
there's any  useable benefit unless you change from the SUs to the Solexs
and maybe swap  in the 3.90 diff center section from a 1600.

Les (CDM) may have some  good used cams, both "A" and "B" grinds. Or you can
contact Schneider Cams,  Web Cams or another cam outfit. You'll need new
rockers and lash pads, too,  especially if the "new" cam is a regrind. You
really shouldn't just swap in  another cam for your current one.

FWIW,
Ron
