hey all,
has it really been almost 10 months?
well, here's an uneventful update:
I don't have a Fury yet. My sis, Mom, my girl and Uncle all made good points. They're all greasemonkeys too btw. They wanted me to be sure this was the car for me, now.
so...
I raced a Factory Five Racing Daytona, Cobra, and Type 33
I checked out a raced-spec Sn95 Mustang
I checked out a 1968 Plymouth Roadrunner 383 4spd
I checked out a 1967 Ford Mustang Fastback for my cousin, he got her, and now is adamant I find my "baby" lol
I also checked out a 1971 SD455 Trans Am and a 1969 Judge GTO
and then there's the real life shenanigans of having a 3 year old.
all along, I've come back to the big C-body Mopars. I just love em. I really want a 1966 Sport Fury. Or a Fury II.
basically, I have wanted a big Fury. But I wanted to check out all the other cars too, while "closing off" anything to do with the Fury. I know she's unique, that's a good and a bad thing. It's harder to find parts, harder to hotrod, and harder to race. But at the same time, how many Furies do you see at your local autocross event or track day? Yeah, me neither
I just wanted to make sure it was worth it. And after a busy summer, and long days at the track, I can honestly say I'm willing to take the bad, along with all the obvious good.
here's what I've come up with using a car that for some reason people love to hotrod and sells for 10x as much, and yet...
1969 Dodge Charger R/T - Forza 3 - taken from oldride.com 69-70 Dodge Charger R/T
Shipping weight Wheelbase overall length overall width front track rear track
3646 117 207.9 77 59.7 59.2
1965-66 Plymouth Fury weight -
http://newcharger.org/mopar-b-bodyc...h-muscle-specs/plymouth-fury-1965-1966-specs/
Curb Weight: 3610lbs(Fury I post coupe), 3665lbs(Fury II post sedan), 3720lbs(Fury III convertible)
so, the Plymouth Fury I in theory has all these benefits versus the big mean B-Body "King"
it's lighter by 56lbs
front track is 2.3" wider
rear track is 1.5" wider
only problem is it's "massive length" which in reality is only 2" longer in wheelbase, and 5.2" longer overall...
HOWEVER, a 1965 Plymouth Fury - same chassis underneath as the 1967, so same track and wheelbase
is
209.2 inches overall in length
yet
78 inches in overall width!
so, she's wider than the 67, yet only 1.3" LONGER than a 1969 Dodge Charger!
the 1966 Plymouth Fury is only marginally larger at
209.8 inches overall length
78.7 inches in overall width
so arguably, the Plymouth Fury can become a meaner pro-touring car, because
A) about the same weight as a Charger - incredibly light for its size, only a couple pounds off my El Camino!
B) long wheelbase can make it a much more stable car at speed!
C) overall width is OVER 6 FEET!!
D) if we can increase the track width to fill out those fenders, which isn't hard... BINGO
She's WIDE, LONG, fairly heavy.... with a torquey 383 or a 440-6/efi
= plenty of power
basically, I could, in theory take the shorter 383 block, rebuild the 383, throw in the 3.75 stroke from the tall block, increase the con-rod length
and build basically a short-deck B block in 426 inches
One of the standard formulas for predicting torque peak given the cross sectional area (CSA) of the intake is RPM = CSA * 700,000/CID. In our case,
the formula predicts the torque peak will be at 3.65 * 700,000/505 or 5,100 rpm. In comparison, a standard port head has a CSA of only 2.88 square inches,
which would result in a torque peak at 4,000 rpm with 505 ci. The moral of the story is that you need to pay attention to the cylinder head volume and
cross section when building a stroker or you might end up with a tractor motor rather than a race motor.

so for my build, 5,000RPM(ish) = CSA *700,000/432
5,000=X(700,000/432)
5,000=x(1620.37)
X= 5000/1620.37
X= 3.08 CSA
my minimum CSA for a 4.28 bore x 3.75 stroke at 6,500 RPM is 2.57
Your Limiting Port Velocity computed from your Cross Sectional Area of 3.08 sq. in. and Bore of 4.28 in. and Stroke of 3.75 in.
and Peak RPM of 6500 is 511.75 fps.

- wtf?!? those are some seriously long tube headers...
- long story short of it, I've thought about this long and hard. I think a 383 Fury, let alone a torquey 440 would be just stellar. They're only relatively longer than the already massive 2nd gen Charger, BUT also have a wider stock track width.
tight, technical courses... will be... entertaining. And thank God they're only cones!
but on open ones, like at the now defunct MCAS El Toro... she should scream.
and on that note, there's a purdy one for sale here in my hometown actually. It's a 68 4 door, not a 66 Sport Fury. But still, it's worth at least a look.
