I recently have been experimenting with advancing my timing. I set it a 16* w/(91oct) and I had no pinging in 1st or 2nd @ 5800 rpms, but in 3rd gear around 5600 got just a little pinging. So, i turned it down to 15*w/(91oct) and have had no pingingat all for 2 weeks.Do you guys think 15* is alright or should I set it a 14* to be on the safe side.

Me personally I would set it back to 14*.

See, i have heard that different timing lights can have different readings and that harmonicbalancers can be different from 5.0 to 5.0. So thats why I thought the best way is the set and test method, advancing till it pings and then back off a degree to get the most potential of a timing advance for YOUR vehicle.

You're right about the test and set. Me personally I like to be a little on the safe side. My 87 is set to 12* I just advance 2* over factory specs.

I had mine at 12*(89 oct) for 1 week, then 14*(91 oct) for 1 week. Now i've been at 15* for 2 weeks. Yea, I know what you mean by being safe cause I'd hate to **** something up from the timing being advance 1* to much.You know 15* is working right now, but its 62 degrees in Arizona right now, i'll probally ping when it 110 degrees here in AZ.

what is stock timing set at? and does it make a huge difference to adjust the timing?

Stock on a 5.0 is 10*, most run at 12* for safety, economy (as much as possible) and advancing it will make it run quicker, but too much and you'll have problems.
