Is it just me or does my 1995 300 not have a distributer hold down screw? I spent about 5 minutes searching for the thing, but couldnt find it! Is it not possible to adjust the base timing without ecu modifications?
There is indeed a distributer hold down bolt, right at the base of the distributer where the casting goes into the block. The base timing is adjustable.
I can't believe i missed it... it had a thick layer of muck on it, but it was still visible. I think it was hidden by the big wire casing laying on top of it
Anyways, i set the timing forward about 2.5 degrees. It would run fine with no knock at about 5 degrees advanced, but i didn't go any further in fear of blowing up my engine.
Thing has a noticible increase in power. It's actually a very noticible difference in power. I am very happy.
