I have gt40 heads and intake with a cam. I think it’s on stock timing I’m not sure but I would like to advance it. I just am not sure how to approach it.
Make sure to have a timing gun and mark the 10*, so you always know your starting point.I have gt40 heads and intake with a cam. I think it’s on stock timing I’m not sure but I would like to advance it. I just am not sure how to approach it.
I would agree most foxes like 14* , just run 91+ octane at a top tier fuel station.Yep. 14* always considered the best
