[6pack] 6 cyl Camshaft results

[n197tr4 at cs.com]

 Several of us are running TILDEN cams in our race cars. It is the best cam
for our purposes and very thoughtfully engineered.

A lot of work and collaboration went into the development and the guy behind
this effort is 'one of us' and brilliant.

You may want to talk to Larry directly to confirm what your needs are. He will
listen.

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.
