  1. My own recommendations...not necessarily the best...is that while the Quadrajet is an outstanding carburetor...there are no new ones being built.  All are very old by now and rebuilt who knows how many times by now...or abused and in disrepair if not having been rebuilt.  It takes a good rebuilder who understands the Q-jet to rebuild one and set it up properly...talents in short supply these days.  Do not...I repeat...do not buy an assembly line rebuilt carburetor.  They will only cause trouble as they're not set up for any car in particular...plus they're just as likely provided only a cleaning and some new gaskets, floats and bushings replaced.  

    I would suggest (as already stated) to get a new Edelbrock Performer (1403) or Performer (9903)...along with a Performer or Performer EPS intake manifold.  The standard Performer intake can take either a spread-bore (Quadrajet and some Holleys) or a square-bore carb (Edelbrock).  The Performer EPS is optimized strictly for the Edelbrock square-bore carbs and posts somewhat better horsepower and torque numbers....but it sits slightly higher so clearance may be an issue.  

    There are good oe-type or performance distributors on the market.  Most any should work admirably.

    I also agree with getting a true dual exhaust...but first check and make sure the frame has the openings on both sides of the X-member for pipes to pass through.  After a certain point some Avantis were only given one clearance hole for the exhaust.  If you can run duals...or even only one...get the biggest diameter pipes that will fit without hitting the frame.  Let that engine breathe!  

    I know this might run more than you might want to spend.  I'm just saying give it some thought about what you want out of the car and then assemble the parts that will accomplish that.  You can always call the tech line at Summit Racing...they will ask you questions and give you solid advice regardless of brands.  You can call Edelbrock for their advice and get probably the same answers but they'll recommend their products of course.  Edelbrock makes great products but they're not the only good name out there.

  2. I can’t speak to #9…but the #8 car has been completely rebuilt.  It’s history is pretty convoluted…multiple owners…less than fine care…several engine changes…a fire.  It’s a wonder the car survived long enough to be rebuilt properly.

    I have a number of photos I took of it when it languished in a shop a few miles from where I used to live.  

  3. A lot depends on the camshaft specs where the engine has its power and torque curve applied.  The 400…which can be turned into a real torque monster…was basically a station wagon engine.  Due to its intended use Chevy engineers gave it a more torquey camshaft design.  

  4. It wouldn't be the blower as that takes engine horsepower to create positive pressure.  The only thing I can think of would be the transistor ignition as it creates a stronger, more consistent spark...particularly at higher rpm's.

  5. Studebaker sent a directive to dealers that any unsold new ‘63 Avantis were to be titled as 1964 models when sold.  That might be one reason the “63” prefix of the serial number was dropped.  That’s why there are many Avantis titled as a 1964 when they’re actually a ‘63.

    Avanti Motors supposedly occasionally did the same…if an unsold Avanti II wasn’t sold until later they titled it as the later model year.  Things like that led to the federal government mandating the 17-digit VIN beginning with the 1981 model year with a model year code in it along with other information.

  6. 1968 was the year all new car production was mandated to have side marker lights.  Avanti Motors had an exemption as a small maker for some safety items which could be delayed but I believe they did start side markers for 1968.

    But for Jeep markers I’ll bow to pantera.  

  7. Yes…all Avanti disc brakes were power assisted.

    I’ve never seen a ‘63 or ‘64 Avanti that didn’t come with chromed valve covers as standard.   Photos of prototypes show painted valve covers but they would have been swapped to chrome before being given new serial numbers and other upgrades before being sold in 1964.  The valley cover was originally chromed and changed to painted black.

  8. The Avanti was the first American car to have modern caliper disc brakes as standard…a big safety point.  There had previously been cars with disc brakes but were outliers in the scheme of the industry…the Crosley Hot Shot had spot disc brakes…whatever spot discs are…but the Crosley wasn’t a good seller.

    A completely padded interior for safety was a great advertising point as well but probably didn’t carry the same cache as the brake advance.
