The better Mopar street Engine

[greg vess]

Always found the six pack aesthetically satisfying. 😁

No doubt! Just the word six pack is enough to peak your interest if not make it a favorite.

Hum! Very interesting you say that. 😎

I was responding to your criteria. Had you asked “which one is better” with no conditions, I’d say Hemi all day. I think it’s the best ever

What do you guys think would be the best street engine.

1. 440 six pack
2. 426 Hemi

When I say street I mean a car that's mildly geared and in full street trim. If two cars we both identical but the only difference being the engine. What set up do you feel would be the better street machine? What say you die hard gear heads?

Greg, the 426 wedge was what was used in nascar racing. That’s not street I know.

I bet most folks that bought one did not leave it stock

All you who like the “six pack” haven’t ever tried to sync three carbs together to run worth a crap, have you ??
That is NOT A FUN combo to screw around with for street running !!
I know, I have been there !!

Out in Texas and Oklahoma most of all those oil well pumps were powered by 413 max wedge motors. Can you imagine how many 413 max wedges are just sitting out in fields out there.

It's not that bad so long as no one else is around.

The best way to do that is with a vacuum gauges. The key was to crack the butterfly until you hit the highest manifold vacuum you can. Then use timing to increase the RPM if it dropped adjusting the blades. The idle screws were a little tricky but with a AFR gauge it wasn't that bad. Where people got into trouble was going after it with no gauges and nothing but a screwdriver. I knew some old timers that could tune them by ear but those old boys were few and far between. Everything is easier with the proper guages.

Totally agree…I vote 440 x 3. Had no issues tuning mine with a vac gauge and timing light w/ rpm readout

The answer to the OP was the 440 six pack. It produced as high a 40+ ft. lbs. of torque more at 4000 rpm.. The hemi just started to make power where the 440 fell off. In order to take advantage of the hemi's full potential you needed a 4000 plus stall converter and a stupid low rear gear, 513 or higher to get the engine up to RPM rapidly. The Hemi was capable of a full 1500 RPMs higher than the 440 and it took the stall and gear to keep the engine up in that higher RPM range to get to the goodness.

and the Hemi takes a lot more timing advance to make it run. If I was given the choice between the Hemi and the 6 pack, I would go with the Hemi, if not for any reason other than it is a Hemi. Either engine is going to give plenty of power and torque to move from one red light to the next with a smile on your face, even it it doesn't take full advantage of the horsepower available
