383 = no love

Actually you could pull this off either way, just tune the one you want to lose poorly...lol
in this hobby we all just have our favourites,and for most of us our favourites back in '69
are still our favourites today.

Nah - the point was taking the bad tuning and driving out of the equation. Again - not a personal choice on winner, just removal of variables.
I won a LOT of races with my 340/4sp E body against more powerful cars because their owners/tuners/drivers sucked and thought they didn't. More than a few sport bikes too. But I had more fun in a 383 powered Newport than any other car I've owned. That car whipped up on a lot of stuff including 440 cars, a 460 Bronco with a single plate system, and a Buick Grand National from a dead stop to 126 where his car shut off. I miss the Cuda, but I own a '69 300 that will be remade into that Newport.

I know a guy who is restoring a '67 Newport with a 440 six pack hidden under the hood.Not a car i would normally pay any attention to, but after seeing this car up close and personal it is gorgeous and is going to be the ultimate sleeper!
 
i ran a twin four setup and then a 6pck setup on my 65 880 rag with a stock 383 cam'd n headers , would take second gear to 6k at 120 then shift into drive it could roll out 140+ . it would open some eyes .
 
Mine was a '71. It was free to me and I was a teenager and did some crazy stuff in terms of spray paint on it. Billboards, hood blackout, a scoop I made functional...lol. Actually got chased in it, got into two fights over it, and was in process of converting to a 440 6BBL and 4sp into it when I had to get rid of it. Still have the hood, and the modified pedal assembly. I'd post a picture but I only have the original physical pictures...lol.
 
as one that has driven big block Darts since I bought the 67 GTS new I am just sitting back laughing
 
I killed plenty of "better/popular" powered rides w/my 383 sdn., 340? Bring it on. That was on the '66 closed chamber heads w/a little of My port work. These kind of
conversations crack me up.

would the longer 3.79 stroke make more torque at lo rpm, say 2000- 2500 rpm?

A while back, the "383 chebbie vs. 383 Mopar" showdown was discussed, Steve Dulcich's B eng. wiped the floor up w/that mouse all around if My
memory serves Me correctly.

Big deal a "boat anchor" 318 could give a chevy 383 a good run..340 will destroy both!!!

I built a 383 Chevrolet for a friend using 350 rods. After checking clearance between the rods and cam, we sold off the 400 parts and changed it back to a 350. What Junk. 383 Mopar: better crank, better rods, stronger block, better flowing heads, no surprise.
 
I just checked out the 383 vs 383 test....they both made the same peak power and torque , although the Mopar made more power down low.
Kind of a silly test really, they should have done a 396 Chevy vs a 383 Mopar.

I believe that may have been, but peaks don't win races, broad torque curves do on the street esp. & the primary thing I wanted to draw attn. to was the short stroke Mopar
had more low-end, contrary to what some would expect.
 
My buddy just built me a low buck 340 (344 inch) , Im going to check my Dyno sheets to see how it stacks up against the 383 inch Chevy and the 394 inch Mopar on that engine masters shootout. Funny thing is my 340 has the same 9.6 compression ratio that their engines do.

I'm sure the results would be similar with 400 vs 408.

The advantage of mopar 383/400 vs 383/408 stroker would be bigger bore size for better breathing and better rod ratios for less friction (hp/wear). Plus can be taking up to a way higher powerband (hp) if wanting to over stroker small block. The only real advantage to the small block strokers is size and weight if you care about that.
 
396/413 would be the best comparison. fairly equal specs.

didnt hurt that the cheby got much more advanced heads then the mopar
equip the mopar with comparable heads, and the mopar would blow the cheby out the water

and a mopar 408 would be a much better comparison to the cheby 383
(or, if you want to give the cheby a fighting chance, a 340 based stroker)
:poke:

I'm sticking to the test is a bit silly statement, one engine is a big block, they are not the same size cubic inch, the cams are different, new heads,old heads, bigger intake volume ect ect.
I still could see testing a big block 396 vs 383 or a stroker small bock 408 Mopar vs 406 Chevy, to me that would be more interesting.

Obviously it's not a scientific shoot out and a one off. I think the main think to take away from it. It does somewhat prove it's more just the size of the engine not how you get there to a certain extent for the torque curve.
 
They should have dropped the engines into the same chassis and ran them on the strip to see which one is quicker, that would be interesting.

I think that 383 mopar worked a little better than most with a cam,intake and carb swap picking up 140 hp.
