400ci Timing?

[jeffdgale]

Hi does anyone know the timing for the 400ci on a 74 Avanti II. Please let me know what the RPM should be when setting. I have a shop manual on the way but it hasn't arrived yet.

Thanks.

Jeff-

The tune-up settings for a '72 400" engine are: timing at 6 deg BTDC (set with vacuum advance disconnected) at 600 rpm (auto trans) or 900 rpm (manual trans) . If you're still using points they should be set with a .016" gap and 29-31 deg. dwell. The specs for your '74 may be slightly different, but this should get you into the ballpark until your shop manual arrives.
