re. 272 sport cam and Jamex airbox opinions

[Alan Kramer]

Carl,
     I have a Schrick 272 solid lifter cam in my '83 CGT.  Although this 
would be a slightly different cam than you would use (since you have 
hydraulic lifters) I highly recommend this cam for spirited daily driving / 
autocross, even at it's $500 price tag.  You can get similar cams at about 
50-60% of that price through other sources.

     I also have an adjustable cam sproket which is also well worth the 
investment IMO.  I run 2 degrees of retard with it right now.  Of couse, 
that's with a milled head so actual retard is probably a bit different than 
that...  The nice thing is you can play with it easily and find the right 
setting for your driving style.

     I have no problems with idle, etc.. with the cam & pulley.  I thought 
idle suffered when I first installed the cam, but I discovered that was due 
to an improperly reconnected vacuum hose and not the cam.

     I also had the car emissions tested last week and passed with flying 
colors with the above setup.

     I run a K&N filter, which I believe might be a slight improvement over 
stock, but probably not much.  I can't comment on the Jamex airbox though 
from lack of experience with it...

     You should also upgrade your valve springs at the same time if you get 
a higher lift cam - otherwise you may bind your stock valve springs.
