Timing 80 degrees off?!?
 

Whoof! Check this out.
I went out to recheck timing with a degree-able timing light this
afternoon and couldn't find the mark. (Been working with octane and timing
to get rid of a slight rattle.) I used a white crayon to mark it, then
orange, then sharpies but still couldn't see the darned thing in daylight.
"Hmm. I'll just wait til tonight."
I finally found it tonight... somewhere around 80 degrees off! (This
measured in cam degrees, so, almost the far side of the balancer.) Since I
totally screwed timing in the day, I eventually tried timing from the #2
cylinder (yeah, I know that's not how you do it but it was almost right on
#2:( It runs really smooth now but motor pings like a can-o-bearings upon
anything more aggressive than smooth throttle (goose it, get on it, etc.)
It's a Chevy 5.7L V8 with TPI and, yes, I disconnected the bypass. I put
the engine together right, numbered all the wires, installed the HEI
distributor in the correct position, put in a new timing chain, etc. So,
anybody had this?
I don't think the timing chain jumped since it's new and slackless.
There's no slop in the ignition, apparently, since the timing light shows
the timing mark's rock-solid steady. Harmonic balancer outer ring slipped?
Ideas anyone? Troubleshooting tips? How many things could it be?!
Drink
P.S. Next time, I'll confirm timing mark position upon assembly and make a
hashmark between the inner/outer ring on the balancer.

Check your balancer against the actual Top dead center using a
screwdriver to follow the piston up.
Chevys run best at thirty eight degree total. Light springs to
reach the total by two grand. I would also mark forty on your balancer
to know your light is working correctly.

That would be my first thought.

Like bill says, find TDC on cyl#1 and go from there.

By the way, plain ol chalk works great for timing marks. That dayglo
stuff or the plain ol white chalk.

Re: Timing 80 degrees off?!?
 

That shouldn't be a problem for the time being, should it? The balancer's
not weighted on the 350 and I should be able to get it timed correctly til I
can get a new one.

P.S. I guess I'll stay off the gas so I don't throw the ring completely
off. I know it's not a hot rod but, man!, I guess I've enjoyed the newfound
power of an injected V-8 over my old 258 <sheepish grin>...
P.P.S. The plan's perfect and going well... I'll just keeping breaking it
and beefing the broke parts til it'll take a magnum round and keep on
ticking:)
