most people mistook my 347 for a big block.

a little over 400 rwhp - rwtq

.590/.595 lift cam EEIV processor with a SCT chip to make all the mismatch parts work.

20 to 22 MPG

Classic Cobra Pack 3" side pipes

I put 30,000 miles on the 347 with no problems

It's all in what you want. There are no rules. I have seen and heard SBF's roar like a BBF and wasn't sure until they popped the hood. But then, we go into the entire other discussion, which will just dilute this thread.....

I would say "bring what you have and be proud of it, it's yours". Plenty of both recipes out there and many more ad nauseam...

The trick to telling the difference is to stand with your butt facing the engine. This allows the vibrations to hit the back of your ear flaps, as opposed to entering directly in to the canal. When done this way, the distinction is readily apparent to the trained ear.

I can tell the sound of a Chrysler or Chevy from a long ways away, even the sound of them starting. But the way guys are building the Ford SBFs now with the "Ca-Chunk, Ca-Chunk" noise and big stuff makes it harder. I will try your scientific method!
