So I just had my block rebuilt. I had them bore it 40 over..so the question is do I have to up my rpm's or do I keep it at factory settings?
You might need to clarify...
What are you asking?
If you are talking about setting the timing after reinstalling the engine, no.
Otherwise you'll need to clarify what you are asking as SinCityLocal mentioned.
Okay before I had my engine rebuilt and bored my rpm was set for 800 rpm(stock). Do I have to adjust it higher then 800? or keep it at 800?
Idle should be set the same.
Manual = 800 RPMs
Automatic = 850 RPMs
It should be on a sticker on the underside of your hood - passenger side.
