I had a '76 Cordoba with a 400,Holley Economaster 4bbl and swapped in a 9-1/4" sure-grip axle with 3.23 gears.It ran 15's in the quarter,probably high 15's if I remember correctly.It however did great burnouts,was responsive,had great top end and handled well on 15x8 Appliance mags with Dunlop Qualifiers.

Compression ratios between best and worst factory stuff ranged from 10:1 measured to 7.5:1 measured. 25-30HP?

Weight is a huge factor. A 1/10th for every 100 lbs.

The 906 heads also flow a bit better stock for stock vs. heads like a 452. 20 cfm best vs. worst is probably 40 hp?

Magnum manifolds vs. log type will do 15-20 HP?

Things tend to stack up for worst vs. best of all of these.

I ran my 67 back in 1987. The short block was stock with 110,000 miles on it and was very tired. It was burning a lot of oil. I had the heads re-done the right way, new guides and valves and a competition valve grind hoping to cure the oil burning. It did not. Anyways, it ran 14.6s at 94 mph. That was with factory intake and carb and 2 1/4" compression bent exhaust with full body Midas mufflers. The car had air conditioning and weighed about 4300 w/o me in it. This was at Tri-State in early spring so the air was good. Factory single point distributor.

I rebuilt the short block put the same heads, cam and exhaust back on but with a six pack and no AC. Out of the box, it went 14.0 at 101. After tuning it went 13,4s at 103 and some change.

Before I rebuilt the motor, I researched all the old car magazines to see what 440 4bbl and 440 6bbls ran in road tests. I found like ten articles and wrote down car/weight/et/mph/track and date. I converted the data to horsepower. The short of it all (I still have the list) is, with the exception of a couple of outliers, they ran between 94 and 97 mph and about the same hp. Et was a bit more variable, but that was just a function of traction more than anything.

70 Challenger R/T

Block 71 440 .30 over Ross Pistons

452 ported heads

Stock rods and crank

Hooker headers

Weiand DP intake

3:55 gears

12:30's @ 112 mph

1969 six pack bee. Auto, 1 3/4 no name headers. 12.80-12.90 105-108. Through the mufflers.

My 73 Charger with a bone stock 440 ran 15.25 at 4200 pounds and 3.23's. I eventually got the car down to 11.40's but it was still over 3800 pounds at that point.

I had posted this back in the Truck section back in 05-06 My dad and My grandfather took delivery of their trucks on a Tuesday in May back in 78, my Dad had a Midnite express truck, and Grandfather had a Lil Red ,that Sunday they ran both trucks at the old McGuire air force base in Nj, The Midnite truck went a best of 14.41(don't remember Mph the Lil red went 14.60 @98.
back in 87 @Atco my 75 D100 step side bone stock 440 no air cleaner with the 727 & 3.90s(not stock) and a set of mccreary tires went 13.96@98 same combo with the A833 Non overdrive went 13.88 @100 Truck with my 160lbs but(at the time) weighed in at 3800.

In 1987(iirc), I re-ringed the original 69,000 mile 440 from my friends 1969 GTX.
Had a valve job done, and installed a Crane 272/.454 hyd cam.
Put an 11" converter in the car with 3.91's and he drove the car from S. Burlington, Vt to (as I recall) Quaker City dragway for the second of the Muscle Car Review magazine shootouts.
Back then any DOT approved tire and wheel combo was allowed and he ran some sort of MT street stickies on the back(L60-15), with something pretty skinny up front, both mounted on Drag Lites(which came off his Challenger bracket car).
I seem to remember it ran like 14.40's out at Quaker City.

When he got back be told me what some of the other guys were running for cams and such, and a few months later there were some articles in the magazine about some of the faster cars at that event, and there were some that had had a little head massaging done to them.

He was interested in going again the next year but wanted to run a bit better.
I pulled the heads, did a little bowl porting and swapped the cam out for the bigger Summit cam.
Put 4.10's in the rear, and got some repop G70-14's mounted on the OE magnum 500's....... Took it to the track here and ran 13.70's with it.

He never did go back to the shootout.

This post has sure wondered away from STOCK engines. LOL

Yeah real fast! I like to hear what people ran with what parts though so I'm not complaining...

9.80's with a stock .030 over 440 block, TRW pistons, stock rods, stock crank, 906 heads.

In 1989, stock 440-6 motor, Team G, 850DP, 2"hdrs, solid Cam....11.2@118 NA, 10.7@125 with just the addition of 2.14/1.81 906's.

In what? With what converter/gears/weight

'69 Cuda, A1 4800, 3000lb, 4.88's, 14x32's...would've gone quicker with a smaller cam than the...290@.050 and if we ran more than the 4psi in the slicks back then!...would've thrown those Gabriel 90/10's away as well, would've done things a lot different today, reckon there was a 10.5 in that car as it was though, only ran it 1 time at 10.7 then hit with spray.

Plymouth Scamp,full interior, bench seat, column shift, full weight car plus 6 point roll bar, chassis connectors, cast crank 440, stock low comp pistons, stock heads, purple shaft .474 cam, torker int 750 vs holley, 1"-3/4 headers, points distributor recurved by me, 3.91 s.grip, stock converter, on very thin street tyres walking it out 13.4 at 104 mph. Fitted an 11" tci converter and 9" slicks ran 12.8 at 107mph.

Bout as stock as we get....Rebuilt 440+.03 and stock reworked heads and some mild gears....No carb or convertor to speak of....And its for sale.

12.55 @ 108mph!

Here was an old test where they said it was "bone stock". Did not touch timing or jetting etc.

Did any actually post a stock engine? Lol. Well, it's just like people touting the "Pure Stock" drags. With a compression bump and bigger exhaust...
Still cool stuff to read.

This is in line with what I think of performance wise for a "stock" 440 HP car. Of course there were some slower, but low-mid 14s and 99/100 MPH seems to have been a pretty common ET and MPH for these cars new when the magazines tested them.

There was one somewhere for a '69 GTX, 440 4 barrel 4 speed 4.10 Super Track Pack car that was 13.6 @ 104.

Here is the follow up to that test, pretty cool reading as they take the car to not stock.

I think mine was awful darn close. It is a little hard to fined someone with proof positive evidence that a car was stock, and have et and mph records (verses memory) to go with that. Plus they would need to be members on here too.

The cars were "stock" 50 years ago, their production numbers wee not that large, and by 40 years ago, most of them were no longer stock. So, what are we left with? Taking peoples real experience and data for close to stock like cars, and attempting to extrapolate what they probably did 50 years ago stock.
