Hello everyone, recently picked up a red 97' Z28 Camaro from a few towns over. Car had been sitting for over a decade, dropped the tank and am currently in the process of replacing the fuel pump at a friends shop. Inside the car, I found what appears to be receipts detailing that a cam was installed at some point. I pulled the driver side valve cover to see if anything else had obviously been done, but it appears to be stock. I haven't fired the car up yet, so I'm unsure if the cam is truly in there (by sound at least). To finally get to my question, if I am unsure of the cam currently in the motor, is it safe to install a set of 1.6RR? I'm more interested in the technical side of this question than the debate over whether or not it's worth it. I tried to research this a little bit but am coming up with confusing answers. I would be very grateful is anyone could inform my uneducated self about the factors at play in the valvetrain and how they are interrelated. This may be a fairly general question regarding small blocks, but I figured since it was an LT1 it may belong in this section best. Thank you

 

Most cams for a LT1 motor would be fine with 1:6 RR but not knowing what lift this cam could be and the "appearance" of stamped rockers which I would also assume motor still has stock valve springs that may not be capable of a higher lift instigated with 1:6 RR without coil bind

Any cam other than stock should be done with new valve springs spec for that cam

I would get the car running first and make decisions from there

Also any aftermarket cam will require a PCM tune

 

Thank you for the info, I definitely agree. Getting the car running first is the way to go.
