LOL.... C'mon, I'm pretty easy I just simply state facts of what the E.T. slip showed when I collect it on the return road....
It was said with 'tongue-in-cheek' .......... :burnout: Go > 318 ~ 2-Barrel

AJ/FormS to be a little nitpicky, I don't see .96 hp per cubic inch race engine territory, maybe they way they did in the 60's. Now days 1.5:1 and above is in the race only territory. 1:1 is more like slightly hot street engine, decent cam 4bbl and headers gets you there.
And the 45 more cubes of a 318 doesn't make hp
If you build a 318 to commando spec it would put out similar hp just at lower rpm with more torque.
In 1965,
The 'best' 1965 273/235 HP Barracuda {Torque-Flite} cars were running
right around 14.05 @ 97 MPH while classed in 'F/SA'
The 'best' 4-Speed cars were hitting 13.90's @ 99 MPH while classed in 'F/S'.
No 'legal' cars were running lower than that.
Not a commando, but I watched a '67 barracuda with a 273 2bbl, auto, single exhaust that was just about as original as you will find. It ran 17.30's. I have no idea what the gears were.
As for me, I've owned 273, and only the 2bbl's. I have never taken one to the strip.
Sneaky Pete,
What I remember from back in 1968.
When the traction was too good, the 273 would 'lag' off-the-line with the
stock Flywheel.
We got a Schieffer Flywheel 'heavy-wheel' which was 38 lbs. We still used a
Weber Clutch-Disc {9 1/4"} with a Borg & Beck Pressure Plate.
It kept the Rev's up when coming off the line.
My totally stock (exc electronic ignition) 273 2 barrel 65 Signet ran a 17.00 with 2.76 gears- in late 80s at 75/80 near Frederick MD
The STOCK 273 Flywheel from my 65 273 weighed 19 lbs 7.6 oz... I replaced the 273's 9.5 assembly with a factory 340 10.5 clutch/flywheel/bell housing assembly!
And the 10.5 340 flywheel weighed 30lb 3oz... And that's why I previously said I loved the way it now launches!!!
Also I use a Borg & Beck Pressure Plate & and my bullet proof SS Z-Bar (I use to break those early a-body z-bars)
Just for chuckles.. The 273 Bell housing was 28 lbs 8.6 oz...
And the 340's Bell housing was 12 lbs 2.4 oz
So I even saved about 5 lbs... Just saying :cheers:

Excellent Post.
I remember back in late-1967, the first time I helped my Father pull that
heavy 'Bell-Housing' off my Mother's Barracuda.
You're right on, as it was one Heavy Freak. Unfortunately, we put it back on
in those days.
Nobody made those 'Z-Bars' back then. You had to modify your own by
trick fabrication.
Thanks 69 Cuda 440
After I had broken some of those stock Z-Bars, I did come up with an easy trick... They flex so much at the ends and go out of round because they are so very "THIN" that they then crack! All one needs to do is make a steel ring and press them on at each end... See Pic as it is self-explanatory! (Modified Stock 273 Z-Bar)
The only real reason I made a new one out of SS is when I did the Bell Housing swap, the original did not fit, so I machined one with the modification incorporated as part of it, but made it from Stainless because I had it laying around and it was tougher material !!! (Stronger even then the Modified OEM Z-Bar)
Oh Yeah, Not only those Bell housings were Heavy Freaks... But so was the A-833 4 speed... I now run with a Passon All Aluminum A-833... Now it's even easier to service the clutch disk... (And Lighter 82 lbs vs. 117 lbs) :cheers:

one would think that the commando with 3.55's would be worth more than a second on this..... kind of strange.My totally stock (exc electronic ignition) 273 2 barrel 65 Signet ran a 17.00 with 2.76 gears- in late 80s at 75/80 near Frederick MD
Put a 273 in a go cart and I bet it would be plenty fast...
Yup that 273's been taking up floorspace for 40 years! Where has the time gone?
I have a 273 kicking around. Since the mid 70s. Never gave it a thought. I bought it for 2 things; the rocker gear, and the 904 trunion tranny. Stuck em both on a 340, and swapped it into a 65 Valiant wagon. I didn't have $500 in it. Boy-O-boy did that little wagon go. Right up until the tranny started slipping. I dropped a slanty into it and sold it to my brother.He was 10 years younger than me, and wasn't into fast cars.He loved motorbikes. Yup that 273's been taking up floorspace for 40 years! Where has the time gone?
Yet another 273 thread pigged up "by 360 is best" BS. An answer to a question never asked.
