Gmpp ls3 480/495 timing using holley
New to the LS world. Just swapped in a GMPP LS3/480 into my 67 Camaro along with a Holley Terminator system. I have not been able to come up with a good ignition timing table for this engine. The file from the Holley site is more for an LS1 and I have read that the LS3 likes significantly less timing. I had my Terminator on my old sbc so I am familiar with the program, but just cant find the timing info to plug in. Any help would be greatly appreciated!!

Here's a thread w/ the stock tune on a 525.
Maybe, d/l it, and take a look at the timing table?
