Horsepower for 69Z 302 w/#140 cam

[Lynn]

Mike: I "get" the vintage build thing, but when you sit down and think about it, I believe it is easier to put on headers, exhaust and gears than to change the cam once it is in the car. I have original exhaust for my car as well as manifolds and smog. I can put them on any time I want to look completely stock.

I am surprised you only have 5 inches of vac at idle. I had a good 10-12 at 1,000 rpm with a 140 cam.
