The "V" signifies the engine was built in Flint Michigan
"0423 signifies April 23
FBA is the engine build code, also known as the "suffix"Last edited by fitzwilly; 12-08-2010 at 12:00 PM.

A few years ago, I bough a book of suffix codes...it is about 275 pages and
has the real and complete set of poop, not a subset like the web sites have....
The book I have is titled MSA-1 "Factory Engine Code Identification Guide"
copyrighted in 2005 by Mark S. Allen
It tells the suffix, the engine RPO, the body, the trans, the carburetor, and smog data.
The book also crosses head castings, exhaust manifolds, intakes, etc.
The MSA book can be ordered by calling 800-600-MSA1 in Missouri. It was pretty cheap, I think $35 or $40 bucks
The web page decoders are pretty bad...usually have only a subset and lots of errors.

Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
