Noise While Drive

[aotte1]

How much noise is their in these trucks driving 50 to 70 MPH.
Noise from:
o mechanical, engine trans dif, 327 with turbo 400 and 12 bolt ( 3.73 or 3.08 gears;
o Wind noise from cab aero, window seal, etc. ( my 86' has a really bad whistle sound over 50); and
o Road noise, body panel creeks, that comes through the body panels?

Say comparing to a newer pick-up. Thinking the aero noise is hardest to correct.

Thanks,
Les
