Hi Guys,sorry i have been out and not able to read or respond to your suggestions.But let me see here.

1. i have a mechanical gauge. (there is no sending unit to a mechanical,correct?)
2. its a somewhat new rebuild.maybe 4000 miles is all.So no,i don't think its time ALREADY for a rebuild.And No, Lucas is for worn engines.this is Not a worn engine.
3.its got hydraulic lifters. (Very quiet.no noise at all.in fact i have never heard such a smooth running quite engine.)
4. it seems like it was reading a little higher before i put in this new distributor.why would that make a difference?
Thanks for the responses.
