More 327 timing issues

So the timing was way off (retarded), so I static timed it by hand to #1 TDC, and rotated the dizzy close to the #1 terminal. Started the engine. It ran very rough and I put the timing light on it and it was maybe 10 deg retarded, so I rotated the dizzy to TDC, but as the marks got closer, the engine died. I tried to start it again, but it cranked slow, then started to catch. I backed off the timing until there was a sweet spot, and it was maybe 30 deg retarded. I checked and checked to make sure I was on #1. Ideas? I doubt my damper is installed wrong.

I had an old ford that the marks were nowhere close. I had to time it like you did. Rotate it close till it would crank slow, then back off till it would start well and idle. Be sure your dwell is set right, and that your plugs are gapped correct first if you can.

Did some digging on the net and the symptom is coming up as a jumped timing chain or sheared or worn distributor gear. Certainly believable considering how long this engine's been in service.

I found out too it could be a harmonic balancer slipped on the rubber.

When I pull up a timing set from Parts America, it comes up as the same set for the later AMC engines. Napa site does the same. Is it the same set?, because I have a new 360 one that was never installed that I could use, if that's what the problem is.

Got home to check out the damper and chain slack. It is very loose. You can rotate the crank about 30 deg before the dizzy rotor turns. Also, the damper with the timing marks will shift on the rubber, but ony a 1/4 inch. I may static time it again and put a more perm mark on the pulley. Bummer. Timing over is coming off.

You probably know but the 327 are famous for plastic timing gears failing. Be sure to clean your oil pump screen if that is the problem, or even if it's not make sure you check it, my gears were changed by the PO but the pump screen was clogged full of left over plastic particles, thought the oil pressure sending unit was bad before I found the problem.

I didn't know they were plastic. Makes sense if the same engine was used in cars. So far oil presure is good.

Do you know if the same timing set is used on a 360? I have a spare one or I can splurge for a roller set.

Does anyone make a direct gear drive set for the 327 to replace the chain and gear setup??

I don't know if they are the same but I know that you can get a replacement set for the 327 with steel gears from Kanter Auto.
