I am running a 2002 carbureted ls1 with a trex cam, roller rocker arms, long tube headers, 3200 stall, th-400 trans, with a victor jr manifold with the msd box. It is running pretty good but I was wondering if anyone out there has a similar set up or would have an idea where my timing table should be. Right now I have 24* degrees inital timing at 1000rpm then climbing up to 36* with it dropping down in the torque curve at 26* and then back up to 36* It seems to be running pretty well but it is the only curve I have tried so far. I guess my question is this curve look good or should I make changes? I was wondering if 36 degree is too much timing for an ls motor or not?
