As promised, here is the latest results from my 'poll':

* a total of 14 people responded to my questions.

* 4 people give strong recommendations for the Isky Z-19
  one person said they got 140 rwhp w/12:1 CR and other mods

* 3 people said they were happy with the GP2 cam
  one person described as mild, but was able to get 110 rwhp w/9.5:1 CR

* 1 person said they were happy with the S-2 cam

* 1 person said they were happy with the TR5 cam, but warned the power didn't 
come on until 3K rpm

* 1 person liked the Kent 'Fast Road' cam

* 1 person liked the stock cam w/1.65:1 rockers - said it really transformed 
the performance

* other cams recommended:
  BPNW's BP270   - described as mild, but was capable of 124 rwhp w10:1 CR
   "     BP285   - better, with more lift and torque
  GoodParts GP-3 - good power - 130 rwhp w/10:1 CR & 1.65:1 rockers
  TSI 275-6   
  Intregral Cams - (http://www.integralcams.com/)
  Oregon Cams    - 1396 for street, 1313 for 
autox(http://www.pacifier.com/~orcam/Mechanical-Cam-Specs.html)

and one that's in development by Tilden Cams which looks very promising.
(http://www.tildentechnologies.com/index.html)

I appreciate all the input, lot's of good information given.  Other point 
brought out were:

Head work is critical for best performance.
Stock manifolds are very restrictive - best performance from any cam will not 
be realized until intake is improved.
Most recommended a CR of 9.5:1 for a street car.
Mixed results on the 1.65 rockers

After all this input, I think my top 3 are now the Z-19, TSI275-6 or the new 
Tilden cam.  First thing I'm going to do is to find out about the Tilden before 
I make a final choice.
