Hey! Does anyone know what I should set the timing at with my 5.0??? I am running gt 40 heads with b303 cam. Someong once told me 12 degrees btc?

 

When you set your timing too high your engine will ping, which is bad. Try setting your timing to 12 or 13 and take a ride. If it doesn't ping then you can try setting it higher, but once it starts to ping turn it back down a degree or two.

Agreed with above advise .Would never go more then 14 degrees.

 

Thanks guys!! runs beautiful at 12 degrees

 

Glad to hear!
