Default Re: poor dyno numbers from 408 :(

I didnt even look at the dyno sheets til just now. I wish I had a scanner so I could show you what the A/F on a carb car is supposed to look like.

I use no ignition advance at all, but the 7AL3 has an optional 25 degree start retard so I dont really get the 'hot start' symptoms.

What cam is in that thing? After looking at the graphs, I'd say that thing needs more valve spring pressure.
