Small Block VS. Big Block

[A383Cuda]

And speaking of overheated, what about these big block vs. small block people! 

Perhaps we should discuss rotary engines.  This is getting dangerous.

Personally...I'd say there isn't anything that sounds quite like a big block   But small blocks rev like crazy.  In a race i'd say 0-35 small block would have a big block car, but after that I think the big block would pull away.  If I had a Demon or something I would only put a 340 in it just because of how fast they wrap up RPM's

So exactly how many lbs. does a 440 engine add in comparison to a 340 ?


more than a fat guy in the passenger (driver?) seat?

Holy Cow! You would think this was a Mopar verses Chevy thread! They are both great engines and both Mopar guys...... Chill!!!!

    I have had em all.  Small block "A" bods, big block "B" bods.  Then I have also owned 9 Hemi cars.   All engines can be made to go fast and all of them have their place.  It depends on what I wanted as to what engine I would pick.............

So exactly how many lbs. does a 440 engine add in comparison to a 340 ?

Mopar rule of thumb:

A small block weighs 100lbs less than a big block, a big block weighs 100lbs less than a Hemi.
100lbs cost around 10hp in hp-to-weight ratio. 100lbs is 0.10 seconds at the track.

So, bugger all difference. 10hp loss when you're making 80hp+ more in stock form.

Ok! im gonna bring my 499 stroker to carlilse and get on the chassis dyno...someone bring a small block and get on the chassis dyno...............rules: pump gas / naturally aspirated / iron headed..................... bring it on... 

[Carlwalski]

Then that would simply be a pocket vs pocket challenger.

pump gas / naturally aspirated / iron headed..................... bring it on... 

Lol, I like how you said iron headed and not stock headed. Beside the w2, are there any other high performance aftermarket iron heads for small blocks? I agree with NZ, that would pretty much be a competition of who spent the most $$$$. The real contest would be small vs. big on certain budgets(5,10,15k). I think the small block might win a 5k budget and I would put my money on big blocks for anything 10k and above.

[nivvy]

well i did mean iron headed mopar factory heads...and of course its about the cash...what else would it be? you have to buy parts........

[KellysCuda aircard]

Well, you all know my opinion, but, when you pull the trigger on a small block at 9500 rpm, a little small block, built right will keep up with the best. That being said, everyone knows why  aftermarket big inch blocks are built (655+ci) .  1500+ horse power on pump gas....muhahahahaha.

I like when I pop open the shaker hood on the Cuda and under that bubble you can see that big old Hemi. Same pretty much with the 440 cars. Has anyone ever thought when you pop the hood on a 340 shaker car, you see the bubble and say, "Where'd the motor go?" Kind of like getting a big deli sanwich on a thick roll and there's a single slice of turkey in the middle.

There's no replacement for displacement and I appreciate a small block. I agree you can get them to run and I'd run one in a car like the TA, AAR or other Mopar where weight and cornering was a concern. For a driver its got to be a better motor for affordability. But for me, I like popping the hood and seeing a Big Kahuana burger between those shock towers...

The old saying "bigger isn't always better" applies here. Street or strip, the small blocks have made their mark and will continue to do so. There's something about the sweet sound of that small block that gets the hair on your arms standing on end. It launches out of it's cage, reving high, screaming like a banshee as it tries to pull the tires off the ground but moves ahead, shifting, then gone in a shrill scream as it passes in front of you in a blurr. The big block finally gets his green, all other sounds are drownded out as the lion roar screams to life, it launches and is trying to twist in half from the torque but lifts high in the air as it blasts out of it's crouched position, it roars past the stands like a hungry lion after it's prey. The sounds of the SB and BB mingle and make goose bumps stand even higher as the lion is about to have lunch, they approach the finish line.....

Big or small, depends what you do with it, if the final results please you, both do their job. YeHawww!

I think everyone here knows it about the cash as far as performance goes..............you can build anything to beat anything.......but it is a FACT.... BIG BLOCK cars sell for bigger value ....hands down...nobody here can deny that! and of course the HEMI's rule there as well! Lets talk about the return on your investment goes as far as performance!!!! Big Block wins again! And I agree with 67vette427, going to a car show most people like the BIG BLOCK cars better!

So overall in real world issue the bigger the better!

The big block finally gets his green, all other sounds are drounded out as the lion roar screams to life, it launches and is trying to twist in half from the torque but lifts high in the air as it blasts out of it's crouched position, it roars past the stands like a hungry lion after it's prey.
