Not a Ford fellas.

I have a 5.7 Vortech with the Mercruiser HP stuff, High rise intake, Webber marine (AFB) 4bbl.
When I put it together I set the timing at 29* full advance. Now after about 50 hours running Im beginning to hear a a little ping.
I always run premium 93 oct. pump gas from the local Haji Mart and also tried a full tank MTBE from the fuel dock.
Still pings in the low power band, 3-4K then it clears up.

The thing runs absolutely flawless otherwise.

Thoughts / suggestions? Too high?
This is the high compression version. Tested at 213 psi cold.

Too aggressive on the advance curve?
What ignitions in it?

What Alan Said. Also are you using non Ethanol Fuel ? Some stations up here offer premium 90 to 93 octane with No Ethanol content. I work a an auto Restoration shop and every spring we get customers complaining about detonation. We ask about fuel and always get the I use Premium answer. We then ask from where... I do not know if this is offered where you are but you may want to look into it.
