1995 Engine question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey guys I just got a nice little 1995 thats lowered front and back.

But was wondering if anyone can tell me if this 5.7L 350ci engine has the factory roller camshaft or what?

Just curious as I may upgrade it later on.

Thanks for looking.

Also wondering if the speedometer can be set by the computer as it seems to be 10+ mph too fast.

99% of TBI engines are flat tappet, The PCM does not control the speedo the Vehicle Speed Sensor Buffer does, Not sure on how to recalibrate it.

Okay thanks for the info.

If you do a web search for DRAC calibration you should come up with some results for the speedo re-cal. The DRAC converts the speed sensor signal to the cluster.

Its probably roller cam CAPABLE, you need to lift the intake off to see if it is
