timing and 87 octane...or even 89
Hey guys
I have searched and found varying results and opinions on this. 351W flat top pistons (10:1 static compression ratio), GT40 X305 aluminum heads, X303 cam and GT40 intake. All my timing is set up for 92 octane right now. Is it possible to lower it enough to run 87 octane? I have seen where some have said don't even try it, so wondering if yall have tried something similar. Been driving the car a little more lately with diesel prices the way they are, but premium is not saving me alot.
