Avanti Power!

[mfg]

OPINION!…… Which of the following Avantis would probably make the MOST raucous, powerful, ‘60’s type’ engine noise, when under hard acceleration, with observer being inside the vehicle?

1) 1964 Avanti—R3 equipped

2) 1963 Avanti—R2 equipped

3)  1964 Avanti— R4 equipped

4) 1967 Avanti—327 Chev equipped

All four listed vehicles equipped with 3.73 rear axles, auto trans, windows rolled up, quiet exhaust system, and radios turned OFF!!

OPINIONS????

I would expect the R4 with the 388 degree camshaft to be the one as far as sound goes.

i would love to check that experience off the bucket list.

I have a 67 327 Avanti and it has a great sound but the high compression R4 with a much more radical camshaft would sound angry.

A couple thoughts:

1) The exhaust sound of a Studebaker V8 is much louder than that of a Chevrolet V8, all else being equal.

2) The exhaust sound of an R3 is notably different than that of an R2.

3) Wouldn't the R4, with its two carbs, make a loud sucking sound when under full throttle?  (I haven't had an R4, so no experience here.)

4) The supercharger of an R2 or R3 will make a nice scream when under full throttle.

5) The more horsepower an engine produces the louder its exhaust.

So, it depends on what kind of exhaust sound one wants.

Good points… however, I was leaning to the sound of the engine itself from inside the passenger compartment. (if it’s actually possible to ignore the sounds the exhaust system produces!!!)

Interesting… and the ‘64 R4 indeed could be the ‘ noise king’!

Your ‘67 327 sounds like a great ride!!

The 300HP / 327 used in the 67 Avanti has hydraulic lifters. The R3/4 cams were solid lifter and noisy.
