Ever hear of ringer cars for tests
383 b bodys are high 14 sec car 15.0 avg 15.2 common
The fastest 383 was 14.4 with a 4spd 4.10 superbee in fact
440 cars were 13.9 13.8 you really think that test is right only 1/10 slower then several 440 b body test or the 69 m code 440@ 13.71
there is hundreds of road test showing 14.8 to 15 .2 you come up with 1 magic time vs the other 50 test
Oh and the exhaust was bigger but nothing else was changed lmfao
You should know better

We went over this once before.

Obscure Mopar people, on an obscure web forum, arguing about even more obscure 60 year old test data lolz.

Like monkeys slinging **** at each other sometimes, I swear.

383/335hp nhra factor rating for stock class racing 296hp based on trap speed 383 was over rated from the factory
68 69 340/275 hp nhra factor rating for stock class racing 295hp based on trap speed 340 was under rated from factory
70 3406pak nhra hp factor 315 hp for stock class racing
71 340 t/quad nhra hp factor 325 hp for stock class racing
Same facts as last time
340 was faster
340 was underated
383 was overrated
340 made more power with a bigger carb

This should be a sticky

Same senseless bs over and over again

In order for it to be a sticky it would need to be useful information that people regularly need or inquire about.
 
The cars in the test were carefully scrutinised for authenticity. That is: is this the car someone would get if they walked into a showroom. Post #16.
The Pontiac entry was disqualified for cheating........& results not published. Among other inconsistencies, it had the vac hose to the dist blocked, & some engine parts did not have the correct part/casting #s for that year. They went to some level of checking to make sure it was a level playing field. Obviously they deemed the differences on the Dodge were not enough to give it an edge.

There was an important lesson in this test: small carb [ 625 AVS ] v big carb [ 700+ cfm Holley ].
both the 383 & the 428 ran identical 14.04 quarter times. The Dodge was 1 mph slower, 99 to 100
 
Something went wrong with the above post, would not let me finish.
I was going to say: would rather have the small 625 AVS & be quicker to, say, 80 mph......rather than a bigger carb carb that comes on 80...

But the superbee had larger exhaust thats cheating big time
invalid test of the superbee

time to bow out of this foolishness
someone cant except facts
 
I watched a lot of 383 Superbees and Roadrunners go down the strip in the 60's. The 323 gear cars were all
15 sec. but with slicks, headers and 4.10's there was one that ran around 13.9. With the 440 heads the 383 compression was in the 8's and they were lazy without gears. You guys gotta' stop believing those magazines.

I can run this if you want, but I don't see where the compression ratio is stated
 
I don't see where this conversation is going, just dyno the damn thing and then go to the strip to get some 1/4 miles times.

I have not been unable to find a good free PC dyno, so I will preset this question for opinions. Around 400, a little more, I think. One thing I do know, it gets up and boogies in a big way. Thank you.

Sorry don't have a clue as to how horsepower would convert to Canadian moose power.
 
Probably around 425 hp without knowing compression and head flow numbers. IF you built the car correctly then you put a higher stall converter in if it’s an auto, AND a performance oriented gear ratio which would allow you to use a 750/800/or even a 950hp carb for even more horsepower and the win ! You have a roller cam and aftermarket aluminum heads, try to borrow a bigger carb and I think you will feel the power.
 
I know why people use them, but my opinion is who cares about the number, it is pretty meaningless. I had mine run on a chassis dyno. The number was 348 at the tire, but it runs 118 at 3290 lbs. The true benefit of a dyno is testing/showing how and where it makes power and logging data. The gross number can be manipulated pretty easily. The most important is unless you have run the car. Any number is given the same credibility of “I once caught a fish that was THIS BIG!!!!!!”

Why build power if it's meaningless ?

The circumstances on how it's tested matters, don't make it meaningless.

I like how racers like to dictate the only valid form of performance is their way.

Many different ways to enjoy and participate in this hobby.

About ten years ago I ran a new small block small less than 300 cid.on the dyno I made approximately 15 pulls on it most optimizing three different carbs, I tested a 600dp, 750dp and a 850 dp race carb off one of my 440s. I also tested the K&N stub stack on the 600 because it still retain the choke.

850 = 459 hp
750 = 455 hp
600 = 447 hp
600 with stub stack 453 hp. + 6 hp

I guess on the street 12 hp isn’t worth whatever drivability problems you might have with a large carb at least not one you would need to go out and buy. As to the K&N stub stack I spent a fair amount of time fitting it too the carb but I’ve been pleased with it’s performance.
 
I think you guys are swell in person, but fk....sometimes, on here, you wouldn't know it.
I remember when I had my 1st beer too though..lmao

Haha
 
If the cam lobes are smooth enough to keep the lifters from getting unhappy before the combos natural peak occurs………should be over 400/400.
Of course, depending on exactly whose dyno service is used……….. the number could easily vary +/- 25hp.
