Mopar Engines ~ "Combinations That Should Have Been Made Available"

-
From a manufactures standpoint, i think Chrysler did a excellent job with their lineup in the 60/70's. Many of "our" combo's would have stepped all over the cars that were the bread and butter of the performance sales thru that period.

With no answer against the Corvette, by choice, i think the only weakness i can come up with is against, the 66' 327/350 Nova & the 73/74' 455SD Firebird's.....Two extremely strong cars for the time frame they were built in.

As far as Mopar's assembly line availability, the W2's & the "over the counter" 3.79 SB crank could have been used, but again, a engine like that would have stepped all over the big block offering's of the day.

Nice,a good honest racer's assessment. Thanks,Rickster .

They should have had an option for a stroked 340 to make a 416 with a crossram intake. Now that would have made a killer combo in a 71/72 Demon or Duster.

Well, Jack, even though Mopar didn't make a SB cross-ram, the aftermarket did. Since Mopar went to Edelbrock for the SB 3-2 intake, they could have stayed with the program for the STR-12.

That combo would have eaten a lot of cars alive.......with some bite. :D

How bout a 833 & a 4.10 Dana included.....Yikes!!!
 
1970 340 swinger track pac STR-12 with a t/a bottom end and solid lift cam.
 
When the 318 came out in 67 should of made a Commando version
 
Am I the only one who wishes Mopar woulda made the Hyperpack kit an factory option for A-bodies through '69? That and a 4-speed, maybe make it the LS package (Lite Sport)...that woulda been a fun car. :)
 
How about a 72-74 10:1 275-300 (NET) HP 400 and 350+- HP 440?

Those motors in an E body would have been good against the T/A
 
A better more potent version of the 1966 Dodge 'D/Dart'.

273/275 HP

* 11.5-1 Forged-True Pistons
* O-Ringed Block Deck

Yup, that is along the lines I was thinking, or maybe making their own casting. It would have made a killer combo with a Hemi type 727 and a Dana 60. Just stick some 340 decals on the fenders and never lift the hood in public. There would not have been much from the factory that would touch it.

1967

Looking at the 'old' Mopar proposals............

1967 Barracuda '383/350 HP' ~ 'B/Stock Bomber' for 1967 'NHRA' B/S or B/SA ={9.50 to 10.59 Wt/Hp}
* 11.5-1 Compression
* 1967 440 'HiPo' Cylinder Heads
* .484" Lift ~ 284* Duration 'Mechanical Camshaft'
* Aluminum Dual-Plane High Rise Intake
* Holley 750 CFM 'Double-Pumper'

1967 Dodge Charger '440/420 HP' ~ 'Super Stock Package' for SS/D or SS/DA = {8.70 to 9.49 Wt/Hp}
* 11.0-1 Compression
* Max-Wedge Cylinder Heads
* .520" Lift ~ 318* Duration 'Mechanical Camshaft'
* Cross-Ram Intake
* Fresh-Air Induction
* Twin Carter AFB's {625 CFM}
 
* High performance head for the slant 6's......maybe OHC and aluminum....or maybe just a cross-flow head.
* As mentioned, a 4-barrel or Commando version of the 318 (not the diplomat one)
* Six-Pack 426 hemi.
* A 4-cylinder version of the slant 6, like Chevy did with their little 153 motors based off their inline 6.
 
Mid-Year 1967 1/2

Valiant '318 Commando'

For the Valiant 'only'........."Junior Stocker Sleeper"

The 'new' LA 318 {260 HP}

* 10.5-1 Compression
* Open Chamber Cylinder Heads {1.88" Intake ~ 1.60" Exhaust}
* 'Mechanical Camshaft' = .461" Lift ~ 266* Duration

bravo, the slant 6 needed a better head, desperately needed EFI later in life and could have used a turbocharger at any time as Corvair had them back in mid 60's, there WAS a turbo built and it ran well. Cross flow would need an OHC. Aluminum casting was not that good back in the day so all that "production 100,000 mile" AL heads and block stuff would not fly. And if they wanted a higher HP 6, they already had Australia's excellent 245/265 "hemi" 6.

This,would be a hoot to drive/race!!
Had a 73 4x4 with a 318. 080" off the J heads(1:88/1:60,worked bowls).A solid Crower flat tappet.(264 adv,[email protected],.470"-.016" for lash. Responsive critter.
 
Well,I like the lady's. "The Bigger the Better, The Tighter the Sweater" I Like my engines in my "A" body's the same! Bahahahha!! :p
 
Imo, what Ma did then was streamline the manufacturing process and leave no room for doubt which motor was the performance motor. For example, after the 340 came out it was the only small block option with a 4bbl. The HP 383 and 440 shared the same camshaft, which was never as potent as the street hemi grind. A 318 commando would have competed directly with the 340. Ma did in a way push this with the 440+6. However with the huge cost and low sales volume of the street hemi she may have left dales on the table by not making a true HP 440, but this would have put the street hemi's reign as king of the street in question.

I would,too....
 
The A279 Ball Stud Hemi that was to take over for B/RB and hemi engines, would of been Kool, every thing that came with a 400 and a 440 after the early 70 ' s would of been a Hemi car. Would of water down the name but there would be a lot of hemis that we would have to be build.

How about a 300+ c.i.d. /6 always thought they needed to optimize the the slant design. Make one with more cubes than Ford or g.m. I do all V8s myself, but thought they missed the boat on that one.
