Got to thinking and had timing chain replaced after balancer failed 5 years ago. Never drove it after.
Took apart today and see that the crank gear is at -2*.
So putting back together at +4 after reading some posts, but now not so sure if I should just go straight up.
Thoughts?

I just wanted to add that I used the XE274 right out of the box in a 1972 400 I rebuilt with the lower compression and I was real happy with the power it had - very responsive and pulled like a freight train. Used stock cast iron exhaust manifolds going into a 3" exhaust system. My driveline was the 3-speed Dearborn trans and 3.23 rear with 28" tires. My engine would fall flat at about 5,600 RPM's and still rev, but no real gain in power after that.
Did you install matching valve springs? I used polylocks and zero lashed my lifters. Distributor timing seem ok?
