Re: '84 crossfire to carburator conversion

by "Ralph Snart" <ralphsnart@[EMAIL PROTECTED] > Dec 21, 2007 at 05:22 AM

Yeah, the C-4 is the red-head stepchild of the Vette family.  I have a '95 
Base Coupe.  It has great 'AWE' factor with anybody out of the Corvette 
family but it's treated with much discrimination within the Corvette
family.

That said, prices for C-4's are low.  So if you're modding a C-4 that's
not 
a Grand S****t or ZR-1 then you're not really doing any damage to the Vette

family.

My '95 LT-1 will outrun almost any stock C-3 and deliver over 20 mpg. 
Name 
any C-3 that can do both.  As for the C-5's, their prices are starting to 
soften and in a couple of years they will bottom out - then maybe they
will 
be treated as badly as they treated the C-4's.

You should look at some of the Corvette forum message boards for ideas. 
As 
much as I hate to say it, Usenet is dying.
