And me, the eternal optimist.  Just one more roll!

I did not know that.  A quick search of "holley remanufactured" did not
turn
up any carbs of generous pro****tions.  Used reular ol' 4781s go for around
$125 regurlarly.

It do add up, especially with ****pping.  I have an unused set of large
tube
Hooker Supercomp headers for the 429 in a 70/71 Tomato.  I ****hed with
them
to try to get them into the '58 before I got all Crites on that sum*****.
#8 tube ****tion would have to be reshaped and rewelded to the flange, and
a
few dents popped out.  I've been thinking of putting them on the 460 forum
in trade for a decent rebuildable 850.  See if that goes anywhere.

As I said over there it will work.  But it will be a restriction even off
the line.  No matter, use it to work things out.
