            ok....for the looks the Charger beat  the Monaco.. ... but for the rest of the specs....why my C-body Monaco 500 cannot perform as well as the B-body charger r/t?  i know i dont have a 426 hemi but i think that my engine is not too far from the 426 specs   thanks!!!             not bashing on anyone...just wondering why!!

Hi
  Nope, I don`t consider it "bashing" at all . Bin there done that . Got rid of it . Build what ever you wish , I was just trying to steer you right. Mearly my $0.02 worth.
I`ve owned a number of C-bodies and loved them for what they were. 
  Cheers !

I`ve never seen one of these in Stock or Super Stock , think there`s a reason?

[73swinger]

I think your torque and HP numbers for the Hemi are a little flawed. Not to be rude either but there is something about the hemi (the heads for one) which makes it perform a wedge style engine. I have a 496 lowdeck (500HP/540 ft-lbs) and don't try and pretend I could beat a Hemicar, If I could well... that's great but I won't count by numbers

[chryco]

I`ve seen Hemi cars get beat on the street by 327 Dueces 350 Camaros 340 Dusters . Why ? They were LIGHTER. At the track it was usualy different though, the hemi would catch and pass them . Voo Doo baby !

Just like Chryco said, There used to be a guy here on Long Island that ran a 289 Mustang that was completely lightened. I saw that car beat a 496 Camaro once.

You could do a big block with aluminum heads, intake, water pump... Install aluminum brakes from SSBC to lose some unsprung weight, light wheels. you know the drill.
Every ounce you take off that car will make it faster.

A while back there was a C body in a magazine with an injected 440 that ran 9's.

We have a member with a Sea-body that's faster then 90% of the cars on this site.

SEA-BODY  i like that!!!!!

[ksdartguy]

Just remember it takes HP and more importantly TQ to move the Sea bodies.
As far as a 383 doing it read this.http://www.moparmusclemagazine.com/techarticles/155_0209_383_engine_restore/index.html
Not bad for a stock 383 with a few bolt ons.

Its more about the right combo of parts.

Here's something along the same lines I noticed too the other day. In the latest Mopar Muscle, in the West Oaks add, they list a Hemi with the following spec's:

426 CID
465 HP
480 FT/L

$13100 (lot's O dough, if you ask my wife  )

Yeah, OK. And then I noticed this down below:

402 CID
435 HP
470 FT/LBS

$5,999  Half off Honey! Uh, Its on sale! (Ya gotta talk to em in a language they understand. That's the key.  )

  I'll bet you that if you put these engines in similar cars they'd probably be real close to the same numbers. The advantage going to the small block I'm afraid. Based on the weight difference alone. Besides, how hard could it be to turn up the 402 to pick up the 30HP and 10 FT/LBS to match the hymee?

Maybe they are too quick for the class? Running 8's in street trim on pump gas doesn't seem to be much of a problem.

Impressive ! Just think how fast that guy could be going in a much lighter bodied car . 
 Maybe enough for 7`s   You can make anything fast , if you have enough $$$$$$
to throw at it.  Even big block Darts .
 Happy Motoring Everybody !!



I`ll bet that`s a nearly stock 318 in there !!!

[jyrki]

Yes, it's an original 318 car! It's a bit hard to see the engine under all the equipment, because the car is loaded, but I believe it's still the original 318.

Hello:
  Looking at you comparision chart, not sure where your 383 figures are from.  But the highest performance 383  ever produced by Mopar was the 1962 Chrysler 300J.  Equipped with special heads and dual quads it only put out 343 hp.
  Given your 4200 lb car thats 12.25 lbs. per horse way short of what you need.  (4200 lbs divided by 343 hp) need 10lbs per hp. at least, better if 8 to 9 lbs. hp.

  I don't want to bash your car or you but, since your on a tight budget it may be better to hold off on spending more on this car.  Build what you want but, rember every dollar spend on this car must produce more power than the dollar I spend on my race car.  Why? Bcause your 1200
pounds heavier than me, and your total frontal mass is much greater.
  Just my opinion.

Don't forget the stock 383 was slowed back on the intake and exhaust.
Just bolt-ons will fix that. Check this article.

[NYrr496]

Lose the torker. You need a Performer RPM on the boat.

Very Impressive ! Didn`t say it couldn`t be done , but ........$$$$$$$$$$$$$ ? No ?
