We might get a chance to try that.  Glen is going to modify his GTS
mufflers.  My Fontana is supposed to be ready in late January.  If
timing and weather works out, I might put it on the dyno and I could
borrow Glen's exhaust for a test.  The outlet on the GTS heads is
much smaller than the 3" pipes and mufflers we used.  I'd like to
test a smaller pipe size, say 2 1/2" but retain the 3" inlet mufflers
and see if that loses anything to 3" all the way back.  Another thing
worth testing would be a cross-over.

That would be interesting.  I'm considering modifying a single plane
intake for EFI for the 408C for the white Pantera.  Throttle body
would be easier.

You and me both.
