Timing help

I have a 79 j10 with a 360. I just installed the edelbrock performer package. I'm having some problem stilling the timing at what degree should I set the timing without the vacuum advance?

If it were stock, it would be 8 (auto) 5 (man). However its no longer stock, so optimum timing may not be the same. I will suggest timing by peak manifold vacuum, rather than timing light.

Bump up the initial timing till it pings under load or you feel the performance begins to drop off, then drop it back a couple of degrees. Keep an eye on it to insure it doesn't kick back while cranking or overheat on hot days. Most times you will land in the 8 to 12 BTDC range.
