Nice Hemi cuda'! How's she do on the quarter?

[TBird1958]

F%^&*%@  A!  Nice.

What's the story here? Is this your restoration work- beautiful!

[Hörnisse]

Nice!  My cousin has a '71 440 'Cuda with the 4 speed.

[Captcolour]

I bought it restored.  I've done a few minor things like the trunk interior, but knew better not to start one from scratch yet.  Found on Craigslist in the Bay Area 4 years ago, hence the name Gracie.

Beautiful metal on that car, loving restoration!

I just got back from a Good Guys car show.  Much, much automotive eye candy there.

Oh wait. That's not necessarily a Hemi right? You got the 6 barrel carb tho right? I haven't got a total handle on all the technical jargon but like em just the same. Hope you're enjoying the whip on this fine day

[Pilgrim]

Six barrels = six pack = three deuces = 3 two-barrel carbs.

US auto slang can be like translating at the U.N.

440 six pack = 440 cubic inch V8 with three two barrel carbs.

Engines like that are why they call the pedal on the far right "the loud pedal."

The Plymouth 440 Six Barrel / 440+6 ("Six Pack" is the Dodge brand terminology) is referred to as a "Wedge" motor, because the combustion chambers are wedge-shaped. The Hemi has hemispherical combustion chambers. Performance-wise, the 440+6 will hang with the Hemi until you get into the upper RPM ranges.
Beautiful car, BTW, but all Mopars are beautiful - even the ugly ones.

Nice! Years ago I saw a road test comparison between two '70 GTXs. One had a 440 4 speed, the other was a hemi. The 440 was slightly quicker off the line and the two were pretty evenly matched until you saw the breakdown of the 1/4 and 1/2 mile times. The 440 was losing steam at the same time the hemi was picking up speed. Pretty interesting.

when i think of hemi i think of the sixties early seventies 426 street hemi. you can find the 'new' hemi in everything from trucks to a jeep cherokee. same name, way different motor.

Yeah, the Hemi idles like a coffee can full of rocks, but it will pull stumps in 4th gear.

Monster torque...Chrysler rated the 426 hemi at 490 lbs/ft @ 4000 RPM.  According to some quick research, the modern Hemi engines vary from 375 to 420 lbs/ft at engine speeds from 5K to 6K RPM depending on the engine and application.

My 1966 GTO 389 V8 was rated at 440 lbs/ft of torque at 2800 RPM, but the original 426 produced max torque at much higher RPM. No wonder it pulled so hard at high speed!

When new, the 4 barrel 383 in my '66 Polara was rated at 420 ft lb. When I owned the car in the late '80s my buddy put it on the dyno at his shop and at 55mph, it was still putting out 390 ft lb.

I REALLY, REALLY miss that car.
