Performance Lacking in a 383 Build.

[Myself]

I just looked up that cam.........waayyy wrong for an aluminum headed 383!! I have a slightly bigger cam in my 9.5:1 iron headed mild 305!

Change to a tall dual plane and a much larger cam and you won't be wondering where your power is.

I have a feeling if we lined up with my little 305 at a stoplight you'd be VERY disappointed in your power.

The motor as a whole is built well, take advantage of it.
