Timing Question

The spec on my 91 L98 is 6 BTDC at 400 RPM, now because of the cam the car wont idle at 400, i need to raise the idle to about 800 but where do i set timing at 800 to?

Re: Timing Question

400 is not correct. should be 6 degrees btdc with the timing wire disconnected at whatever idle is set to, usually around 750 rpm.
