My Feedback: (8)

Try a hot plug like an O.S. A3 or something similar...but it will also help to know how much nitro % you plan to use?

20%, his dad ( a NOOB who thinks he knows alot....) is going to use my A5.... I said bad idea, but we'll see

nah, tell him to go with a hotter plug for an engine like that. If you go to like 25%, go with a 5 or 6

Os A 3 McCoy 59, these are both hot plugs, medium plug OS 8. General rule of thumb on a small block you run a hot plug unless you are running a high nitro content then you run a cooler plug.

Well he is running my A5 for the moment, but it is running very rich (for break in) so we'll see if it works when he finishes breaking it in, or i'll buy a new one for him when I go to the hobby shop. thanks for your answers

Probably after break in you're gonna need a new glow plug. Get a medium one.
