Hi tech engine management certainly doesn't hurt either but put a 727 and a 2.76 behind it in a 5500 lb Ram pickup and I think the experience will come up somewhat short of sporty. Peak torque on a Gen 3 is 4000 rpm +/-. On a 440 it was 2800. Kevin [/quote] How many hemis or 6 packs came with a 2.76 gear? [/quote] lLots of them with 3.23. Kevin

V.W. did I should have qualified that with American Cars subject to EPA and CARB for emissions and EVAP reasons. I know from my Dodge engineer ('62 - 2005) friend EVAP is what killed the 3X2 because Holley would not do the EVAP modification to all three carbs even though they (Chrysler engineers) had already done it. Bet it was too late and to close with all of the EPA/CARB emissions regulations already all most to the end of the two year phase in to even consider dual quads for any model. As I said they could even get the 3X2 carbs into production at that point.

They already had their flagship performance motor with the dual quads. Most guys who bought 440's were looking to save money over paying up for a Hemi. Not many would have paid up for the 2x4. All this hogwash about the dual quad Hemi not being a good street motor will never die. I know from thousands of miles, they are the best street motor. Huge torque AND high rpm power. Very smooth, reliable and easy to drive and maintain in stock form.

They didn't do it because they didn't need to and/or they didn't want to. Mopar could've turned the wick way up in the horsepower wars but they didn't. Most likely because that wasn't the business they were in. It would've been very easy for them to put a 4.250 stroke crank in the 440 and make it a 505. They could've added the MW heads and a dual quad intake and buried the competition. Those parts all existed in the early 70's and hot rodders had built similiar combinations so they knew it was possible. They didn't need to do it and nobody really wanted to do it so it didn't happen. I suppose they might have regretted killing the big block since GM was able to keep their big block around in the truck division. Mopar probably could've done a truck version of the big block and kept it around a bit longer. GM is still selling big block crate engines but Mopar exited the business. I just got a new 632 from GM last week. GM is selling these 632 inch big block complete with EFI and coil near plug ignition. Makes 1000 hp on pump gas with a hyd roller cam so it will work great in a street car. Mopar could make something similar if they wanted but obviously they don't since they haven't.

The block hadn't done well when they put hemi heads on it originally just as issue's resurfaced when Indy brought out the 440-1 years later, Why Chrysler never made a dual quad 440? Why would they.

And I'm positive I missed a few. I think the 426 Hemi had two cams as well but just can't recall. Accountants hate part numbers, I bet they were positively bezerk back then based on my time working for Mopar in the 80's. Reduction in part numbers to increase the profit margins and save money was a constant mantra. Last edited by gdonovan; 12/26/22 09:40 AM. "I think its got a hemi"

As small was Chrysler is to the other 2 they had a DQ intake for all 3 early Hemi's, the Poly, both low deck and tall deck B, Crossrams long,short and 1 pc and 426H intakes I would think they would have had it figured out as good as anyone and better than most.

You think that is bad how about ford? They had twice as many different engines, often 2 or 3 of the same size that were totally different engines with nothing interchangeable between them... talk about a cluster! GM wasn't much better with different engines for buick olds pontiac cadilac chevrolet... all getting their own engines and sharing engines sometimes. Chrysler had like 3.5 engine families in total thru the 60s and 70s I am not causing global warming, I am just trying to hold off a impending Ice Age!
