Well, I'm running a 281 motor. I don't have use
of a dyno right at the moment, but when I had it
here, it seemed to do well with timing locked
and set at 20-21 deg. Made good power from wide
open down through to 1000 rpm anyway. I played
with the dist at 1500 rpm and at 1200 rpm and it
seemed to like the same timing. With some better
tools I can be a little more accurate the next
time I have the dyno.
I changed dist last night to the 22 deg with
light springs. Started with a base timing of -1
and full advance was 21 at about 1500. It ran
and sounded like $h!t untill it got at least 10
deg of timing in it. That was at 800-900 rpm.
This motor seems to want timing down low, but
not too much up top.
Like I said, with better tools, next time I have
the dyno I will be able to get more accurate,
but I have a good idea what it wants right now,
and that's a small amount of advance coming on

|try at 15 base. mind ya that when the advance kicks all in, itll jump up to 37 degrees at 15, which will result in power loss on the dyno. BUT, if your overpowering the wheels now, its a good way to take a lil power out of em so they will hook up easier and has gained distance on the track. think of it as a shock absorber! been running a 400+ci smta on dyno n set at 15 base, no advance, set the timing at 1000 engine rpm n she runs just fine! pto wont handle it unless a big guy hangs on the pto lever to keep it enguaged. lol. |
