Title: a few questions
Post by: L79_Acadian on May 27, 2014, 05:11:07 AM

Hi I need some help here. I have a stack injected small block chev, on methanol.
Now I would like to know, what weight oil I should run and what plugs?
The plugs need to be gasket seat,3/4" reach nonresistor, for a mag.
 Thanks guys

Roger:
 We need to know more information on the engine.
Do you know what the bearing clearances are and how much compression the engine has?
I see you posted this in Matts engine section.

Thanks: Matt

My opinion

  If you are running alcohol then use Brad Penn oil, weight is a preference
  As for plugs for right now to start just a standard set of NGK b9es, you dont need anything trick or high dollar. Real easy to read since they are cad/iridite plated--dont go beond three threads of burned off plating- 4 threads is too close
