RE: GTV6 L-jet mods

Well I want to know, how high do you actually rev this beast?  Are 
you serious about 8000?  That seems nuts.  But what do I know?  (I 
suppose if you have aftermarket connecting rods and valve springs, 
it's really not that unreasonable.)

To answer your question, yes.  Tachometer quirkiness is a theoretical 
possibility, but I've never heard of a tach *over* reading by that 
much.  Mine over reads by 200RPM up to ~3500RPM, but by the time I 
hit the 6400RPM limiter it's *under* reading by 200RPM.  I suppose if 
the PO messed with the ignition  it's possible that some kind of 
aftermarket ignition system has been configured to work with a tach 
from a V8 car and is consequently making your tach read 33% high, or 
some such nonsense, but I think that's also highly unlikely.
