Mine likes 18 initial 33 max mechanical and the vac is mostly un functional

Safe start is 34 total @ 2500 rpm, add/subtract to suit compression and fuel.

Set idle to suit your taste which will depend a little based on manual trans or auto+converter.

Exactly.  There's no specific set of numbers for these engines-it's whatever works for your application, but the numbers posted above are good enough to get you started...

my 512 is 25 initial, 34 total @ 2200

Thank you for the information.  Needed a good starting point and will go from there.

Thanks
