Timing for a chevy 1968 307 small block
 
i read a book and it said 2 degrees btdc but i know some people advance it for better performance, what should i set it too to get more power maybe 4-6 degrees???

mostly, we set it to 12 degree`s btdc, with 38 degree`s total advance all in by 3000 RPM, I`d start by advancing it up to at leat 8 to 10 degree`s BTDC just for starters to see what it runs like, if detonation is heard, slow it down 2 degree`s at a time until it`s gone and it`s set. I noticed on your other post your still running points, the best place for points is in the trash. while a HEI is the best way to go, you can also order a pertronix point eliminator kit, it fits inside the distributor your using now, it simply converts it into a electronic unit, it would be cheaper than buying a used HEI and rebuilding it. the points being bad or out of adjustment will cause the backfiring problems.

Run whatever timing that you can get away with without it pinging. The more you advance it, the more likely it is to ping (detonation)

If you go up a hill in high gear and step on gas, if it pings, back the timing off a little.
