camshaft issues

[streetxj]

The Mopar cams do improve power over the late model cams even though the duration is less 'cause as I stated earlier, the overlap is less and thus the dynamic compression is more. Compression ratio calculator from Jeepstrokers: http://www.jeepstrokers.com/calculator
The dynamic comp from the renix/obd1(87-95) installed -8* is 6.36:1, installed straight up 0* is 6.82:1. The dynamic comp from the 96-01 cam is 7.47:1. Install the Mopar 28 straight up and it is 7.73:1. Install the Mopar 29 straight up and it's 7.56:1. So with the 28 you have more low-end torque and have it earlier, and it lets more air in with lift at .43" compared to the 87-95's .424" and the 96-01's dual pattern .408in/.414"ex. The downfall with the 28 is that the power drops 500rpm shy of redline(no biggie).

Oh okay. Now I see how it works.

Any info on these in regards to smog. I'm in Cali and have two 97s. I'm wondering if I did a mopar purple cam swap would it affect my ability to pass smog.

Bmarsh,

Just curious to see what CAM you went with and how it has been holding up after this amount of time?

he hasn't been here since Sept. 2012-- he may not get back to us any time soon....

Thanks - just hoping. I don't stop by all that often as well so I figured it was worth a shot. Curious to see some of these threads end with some resolutions.
