Brian, the Autolite 3923's and a 180 thermostat
did the trick for my '98. I use 87 all the time now
and absolutely no knock! BTW, make sure you
don't have the dreaded belly pan gasket leak in
the intake manifold. Been using a little oil lately?

<< I have an engine knock that I can not get rid of. 98
318 I have a jacobs pro street ignition running
3923's. (using 87 octane)If I get on it a little more
than half throttle going up hill she will start to
knock until I let off. If I continue using only a
little throttle she is fine. I do not want to settle
for a truck that has the power to hall butt but can't
because of knock.
Should I just go back to running 89 octane. Just put
in the 3923's but did not help much.
TIA
