There is a lot of misconception "out there" on the Max Wedge Engine.
Hopefully, this will shed light on the subject and clear up some long existing controversy.

From an article in Auto Restorer, July 2000

QUOTE: "The effects of ram induction are useful over a narrow rpm range, so engineers had to tune the engine for the specific range. With the Max Wedge, the length of the runners was set to optimize the torque from 3000 rpm up, as the engine was intended for racing purposes only, even though some Wedge cars did duty on the street. Hard starting and slow warm-up on cold days added to drive-abilityproblems already exacerbated by a high-output cam and lots of compression. Some cold weather, high-humidity days could even cause icing in the inlet tract. A piece of cardboard in front of the radiator helped a bit, but the engine never was happy when cold. All the raw fuel running into the cylinders when the chokes were left on for an extended time washed down the oil off the cylinder walls and added wear.
The carbs had manual chokes, and keeping them open a bit so the engine idled at 1400 rpm helped a bit, but made for an interesting few feet when the automatic was engaged. Chrysler didn't have a four-speed capable of taking the torque. so only their hell-for-stout warner T-85three-speed, or the A-727 Torqueflight were fitted, most of the cars were automatics and raced SS/A (Super StockAutomatic) class."

The article goes on about the Hemi "Looser" torque convertor being available later in 64/65 and that helped a bit AND the fact that it was an "ANIMAL, a Max Wedge.

The point is: These engines were "not nice". Period!
If you had one or do have one, they were hard to start, FLOODED regularly and were very temperamental.


It is clear to me the "Street Hemi" was and is a milder Animal, not the "Un-ruly"beast that the Max Wedge was (is).

I am lucky enough to have a Dale Reed built 440 as a Max Wedge.
He told me quite frankly on a Friday afternoon, November 2008, the 440 would make me happier.

Thank you my good friend Mr. Dale Reed.

afb's with cold intakes were never happy on winter days. i've seen street hemi's frost up back in the day. afb's with cold iron intakes are darn near impossible on winter days. i've used the 308-.520 stage 2 cam back in the day and never thought it was a hot cam. long slow ramps and a wide LSA. when i was a lot younger back in the '60's i wanted one. i had a stage 3 motor and '64 ply 2dr sedan body. never got a chance to put it together.
 
Quick story,A friend of mine had a 62 Maxie Dart back about 1968 when he was a teenager.Something was always wrong(He drove it on the street)Fouled plugs, carbs adjustment, timing, points,spun bearings etc. Now in his 60's he bought another one,Spent 50 grand on it.. Guess what, second day blew it up,spent a fortune on repairs and still,,,,,fouls plugs,messing with carbs,Still wants to drive it on the street like it's his PT Crusier,you get the story,,,"Steve did you think things would change just because it's 50+ years later?"He laughed and said "I guess my memory got the best of me".We are still kids at heart. And still love those tempermental Maxies !!

the mentality back in the day was "rev the $h!t out of'em". everybody did it. spun rod bearings were the norm. i'd bet 90% of all 409, 427, 413-426 casulties were running them out of oil and spinning a rod bearing.
 
I can only tell you my current experience with stock 3705 max wedge carbs and stock cross ram on the street. Car in question 64 Fury convertible, 5 speed manual, 3.55. Engine 10.5-1 446", Eddy heads opened to max wedge. Its had 2 different cams Comp [email protected]/.520 and a larger Comp hydraulic roller. Car starts right up in 40 degrees or warmer w/o chokes. Idle fine after about 2-3 minutes of warm up. Drives great, no stalling, excellent throttle response, 15 mpg on the open road. It does have MSD 6A which I'm sure is better than the points were. As far as oiling and bearings The only difference between the max wedge and a 440 is the oil pan. If you're constantly spinning bearings there's an assembly issue.

Funny you should say that "rev the Sh## out of the thing..."
Yes, these engines lived in the 6500 rpm and above "range"
So true!
Now of course, they are highly collectible!

...blah blah blah hard starting blah blah temperamental hard to tune blah blah iced up intake blah animal blah blah.

So what? Sign me up, I still want one. :)
 
yeah what he said , unhappy sign it over ill give that hard starting pos a great home
 
Good read! I have to admit that I have taken advantage of modern tech (Edelbrock heads, hydraulic cam, etc.) to give my max wedge better street manners. It's still a handful but better than in the day. BTW, Dale Reed is the man! He built a 410 stroker small block for my '65 Barracuda. He told me he rarely does small blocks. The one he built for me makes gobs of torque and runs strong!
 
I just gotta add this...any Max Wedge of any year/compression/induction has nothing on starting than my old lawn mower. That damn thing would make BOTH my arms sore just trying to get it started.

Now back to out regularly scheduled thread......

Reminds me of a night "on the beach club" scene in Narragansett RI back in 1975.
Perhaps 0130Hrs and I'm heading home on the Harley FX (1200cc/74 CI kick start SuperGlide)
I kicked it for 45 to 50 min.
A "no-start".
Turns out i was so drunk, I had the Kill Switch on (Rt.side handle bar above throttle)
Funny thing, I never hit that button "off".
Someone must have walked by and flicked the switch!
But, I sobered up kicking it. (not really but WE all use to drink and ride back then)
 
my 64 Plymouth max wedge savoy survivor car was a bear to drive on the street.
mine was set up exactly from the factory with the original ball n trunion driveshaft right down to the winters converter with basically no stall speed.
My carbs were set up perfectly, metering jets and rods staggered jetting and my 3705 carters had the cable choke,
mine started fine ,warm it up and go but the go part was the tricky part.
You needed to feather the gas with the foot on gas and one on brake pedal, then pushing the button into 1st gear gave you a nice jolt forward almost wanting to stall out ,with the 4.56 gears and trunk mounted battery made for a hairy ride once getting going.
my spark plugs j11-y champions always looked good. it was all in the jetting to make these cars idle and run good.
my savoy had 2046 original miles all at 1/4 mile at a time. Car was a track favorite at Piedmont dragway.
 
I forgot to say mine was a aluminum front end car. i'll have to scan some pics of it.

From the sound of it, would appear much of the problem of max wedge on the street had much to do w/ the factory converter and idle speed. Nowdays, there are plenty of race cars running on the streets w/ huge roller cams and automatics. However, converter technology has come a long way since then.

Would love to see pics!
