203/208 .450I/.460e 116 lobe sepration all with 1.5 rockers

 

'97 LT1 cam specs are:

201/208, .447/.459, 117 LSA - 113 Intake Centerline

 

so is it 201 or 203 ?????

and does anybody have flow data

 

There are some cam specs in this article, none of which agree with the above:

Rebuilding the LT1

They don't list the 97, but I would suspect it is the same as the 96.

For head flow data:

Headflow Comparo

 

I'm pretty sure the specs I gave him are correct - the specs for the '97 cam are slightly different than '96 specs.

 

i heard the 97s had a little improved head flow also. i didnt know if it made that much difference or not

 

'96 and '97 LT1s have '561' castings which flow a few more CFM than the '93-'95 heads. Go to http://www.advancedinduction.com/ ...there are flow numbers for stock LT1 heads which are pretty representative of average LT1 head flow numbers.

 

well either desktop dyno is gay or GMs running the impossible cam
i put in 200/208 .447/.459 with a 117lsa and 113cla and the cam math tool on DD said it was impossible. whats up with that
