Volva Penta 5.7L Vortec Timing Curve Wanted

[John_S]

I picked up the following from a Volvo Penta owner's post, but would like to see the complete curve, if someone could post it. I am not looking for a specific model/year just any factory 350 vortec to compare to the Merc timing curve I am using. Thanks.

RPM Advance
600 3
2200 20
3200 26
4800 28

Volvo used 2 different distributors on their 350's. Between 94 and 2000 they used the Prestolite BID system. From 2001 they went to the EST distributor.
All are with 89AKI Fuel.

Thanks Don. That obviously doesn't match what the other poster said. ??? It did seem like they were quoting from the service manual. hmm. Thanks.

A poster on a different forum. He actually posts here as well, just hasn't been around in a few weeks. I had previously PMed him. I'll see if he has additional data when he returns.
