My engine guy just called and ask me several questions about my build. One thing he mentioned was that if I am going to use the stock distributor I need to have it machined for 20 degrees initial advance to work good with my cam. I have never been any good at this area of tuning. What say the pros here.

My cam specs are..

289/299 advertised duration
231/237@50
Lift .563/.560
On a 112 lobe sep. The cam card will reflect an advance of 3 degrees.

full roller
stock F heads
10.0:1 compression
stock intake and exhaust manifolds
Will also have power brakes and A/C.

What distributor are you using?

I was going to use a stock 70 442 automatic distributor but if it has to be modified I will use a standard 455 distributor.

I just talked to another member and think I have a better understanding for what I need. I will have to talk to the engine guy again because I think I may have some terminology wrong.

Here's a simple view, I know it's for a chevy but the principle applies to all V8's.
