I'm not having any luck finding the specs on my stock vortec 5.7L engine that came from a '96 Silverado. What I need are the stock cam specs and the stock piston to valve clearance so that I'll know how much lift I can go with on an aftermarket cam without having to worry about clearance issues. Any suggestions on where I could find this information ? Thanks, Ron.

I found some information on the 5.7L Vortec engine, and I wanted to post it in case someone needs it in the future.

The stock cam specs are: Intake - 202 duration / .410 lift; Exhaust 207 duration / .424 lift with 115 deg lobe separation. The compression ratio is 9.4:1
