First , I want to start by saying thank you to everybody who helped me out last month
I swapped my engine , now the engine is running and tonight my stang hit the road again

I have a little question about timing .... The engine I put on my car is a 5.0 .....pretty stock with a camshaft (B303)...well , this is what the guy told me ... mass air flow ... H pipe ... basic stuff like that

Should I change the timing from "10 degrees before top dead center" to another timing because I changed the cam? I set the timing to 10 degrees before top dead center and the engine works , but the idle is bad a little bit ...

Is it the standard setting or I should set the engine to another timing because I changed the camshaft?

thanks a lot again!!

5.0 engines like 14* timing but usually requires the use of 91 octane fuel.

Thanks for the fast reply!

Ok so there is NO relation between camshaft and timing , am I right?

If I don't use 91 octane with 14 BTDC ... the engine will suck ?

No but you will more than likely have pinging and detonation which is not good at all for your engine.

OK thank you very much

12* is a good comprimise.

cam timing and ignition timing are two seperate things.....cam timing controls valve timing events where as ignition timing controls spark timing/ delivery = early or later
