AutoX,

For an A body with at least 3.91-4.30 gears with a 3200-3400 stall 9.5" vert and a HR cam in the 236 @.050 range on a 110 split in no later than 106. Performer RPM or AG intake is your best bet and a tweaked downleg 650-700dp. A 10.5:1 340 with at least 255 cfm of intake port will get you right at 400 hp in a very streetable low 6000 power range. That's plenty of airflow potential for that 400 hp range.

Heads are really key, the old iron can be pretty darn good if you know where to whittle.



I'm sure that is streetable and you can drive it on the street. No doubt.

But what I was getting at is that some people don't like a rumpity loud cam, like a low idle speed, enough vacuum for power brakes, etc.

Each person has a different threshhold or expectation for that. IMHO, that many times is more of a constraint than the parts you can put in it.
