Title: 15 MPG!
Post by: Snotty on July 08, 2008, 12:09:42 PM
Hey all, a week ago Jerry and I swapped the 3.23 gears for the original 2.76 third member I swapped two years ago.  (For those of you worried about my surgery, Jerry did all the lifting.)  We drove to Redwood Christian Park last Sunday fro Family Camp.  I took the Newport because it's the only car I have that has a large enough trunk!

Anyway, I got 15 MPG!  Yes, I was happy!

So, swapping the original intake and carb for the Performer and 750cfm Edelbrock setup was the way for me to gain the mileage I so desired.

And, my car ran much cooler than before as well.

It was fully loaded and we had four adults in it.  I think I might get a little better with an empty car.

Whoo-Hoo!

Was that mileage reading taken before or after the buffet? (http://moparfins.com/forum/smileys/smiley2.gif)

Very Good Scott
 
Since Mobby is looking for a formula for his chrysler, maybe that is what he needs to do.
 
I've heard this before

   Is the intake the standard performer or the performer RPM?

i already have a 750 carb, and the 2.76 rear... stock intake manifold and gotta do the timing set, get the engine mounted in again... probably should get that dual exhaust done too...

the way i am now... 8mpg seems to be the magic number.

The worst of my C's was my Polara, I was lucky to see 15 mpg.  However I must admit that I drove that car in a fashion that would make Mobby proud.

I put over 60k on my '66 NYer and never got bad mileage from it.  Even around town it would average 14-16 mpg NO bull sheist!  It's highway average was 18-20!  I kept the car in good tune and ran Sunoco 94 (around a buck-40 then... (http://moparfins.com/forum/smileys/smiley7.gif))  I remember this very well because the car's fuel guage didn't werk for the first five years I owned it.  Fill-ups were based on distance travelled.  Someone on the old board argued this point with me saying it wasn't possible, I wish I still had the gas slips to prove it.




 
When it came to poor fuel economy, my '64 Land Rover was second only to the space shuttle on lift off!  At least it was capable of climbing a tree, whereas NASA's stable only contains vehicles that can go into orbit, land like an airplane, and sometimes mysteriously explode.
 
Anyhoo...  Great work Snotts!  I wish you a speedy recovery so your son doesn't have to do all of yer heavy work!

My new Yorker averages 16.28 MPG on the highway,12 city.
Ross' Monaco fairs well,too.
During our road trip to National Moparts last week,we thought Moparmatt was in front of us with his Cadoo-ack which appeared to be gettting excellent gas mileage!! (http://www.moparfins.com/forum/smileys/smiley17.gif)

Hence the reason I've been thinking about a TBI 350 transplant in the Coupe DeOldsmillac.  It averages 14 mpg with the original 3.91 diesel 10-bolt axle.  Engine and ecu donors are plentiful!  The car runs just fine as it sits, but feeding it is another issue.
 
It'll never achieve Polaraco's status but it'll be a freak no matter what I do with it.  Currently, I'm striving for the it-still-runs, no-original-paint and all-surface-rust look (http://moparfins.com/forum/smileys/smiley4.gif)

Dare I ask what you're using for your wedding car?  My '66 NYer served in two wedding processions, my phat sister's FIRST wedding and my first (http://moparfins.com/forum/smileys/smiley11.gif) (http://moparfins.com/forum/smileys/smiley7.gif) (http://moparfins.com/forum/smileys/smiley19.gif) (http://moparfins.com/forum/smileys/smiley7.gif) (http://moparfins.com/forum/smileys/smiley2.gif) then Siss came along...  the rest is history!

My '60-NY with 500" engine and longram-intakes with two 625cfm carb AND 3.91 gears in the rear got 11.5 MPG on the highway some time ago.

Just FYI ;)

I home again!
 
It's the standard Performer.  Since my motor is stock in all other ways I thougth the RPM would be over-kill.  I am running duals as well - 2.5" all the way to the rear.

I've noticed there is usually a big difference in fuel mileage between B and RB motors.
 
My 383 in my 68 coronet would bet 22-24 on the highway and 16-18 around town...3.23 and auto. 
 
Well I'll see what my mileage in the wagon goes up to when I rebuild the bottom end....right now it's got over 100K miles on it.

I think the main difference comes when the 440 is involved.  The NY I had had the 413 RB.  I was very pleased with the MPG I got with that motor.  When I first drove it a long distance (Interestingly, it was to RCP where I drove my Newport two weeks ago.) and got 18 I was estatic!  When I read that the '62 NY won an award for best MPG for a "luxury" car, at 18 MPG, my baloon burst.  I thought it was "me."  Turned out to be the car and motor.  (http://www.moparfins.com/forum/smileys/smiley9.gif)
 
My parents got 17 on a trip to Louisiana in '67 in our '65 383 HP Newport.  That was fully loaded with four people and luggage.  They were pleased.
 
I think it may have more to do with cubic inches than anything else. 
 
I averaged 18 in my '93 B250 Van with 318 magnum.  A buddy gets 13 with his '96 B250 that has the 360 magnum.
 
I'll tell you, the best car I've ever had for MPG and comfort was my '70 Challenger with 225 and A230 3-speed.  I got 27 on the highway!  I loved it!  It had great looks and mileage.
 
Wish I had it still.  (http://www.moparfins.com/forum/smileys/smiley19.gif)
