I just getting done with a intake, head, cam, swap (see sig) and have heard that you should run more initial timing with an aluminum heads....

I don't have a way of datalogging yet so I'm kinda in the dark about where the car is pulling timing out if it is actually pulling some out.

I have set my initial timing as close to 6* BTDC as I can.

Do you think that I should just keep bumping my timing up..... Some have said that they run as high as 14* initial timing.

I thought that the cumbustion process is better with these new heads which would mean that it needs less timing.

ANYBODY?????

 

Each engine is different.
I'm running 8 deg btdc.
Aluminum heads allow you to run more total timing due to the heat transfer rate being much better with AL vs. iron.
