I have had both.
My max wedge is very driveable despite its big cam and higher compression
but I use the NASCAR intake (Rev 2 )which was a intake , single 4 barrrel
developed for circle track racing these motors. If you go to
dropshots.com/Dolmetsch you can find a couple of videos of it cruising. I
also sustituted my private grind hydraulic cam which is almost the same
specs numerically as the max wedge orignal but eliminates the valve
adjstment routine and the racket from the solids. It also makes more power
having more lift (becauseno valve lash to be subtracted from ift figues
(Solid ligfter valve lifts are given at zero lash which is ridiculous since
no solid lifter cam runs at zero lash) and a hydraulic has a bit more
effective duration since it isnt being spent snugging up the lash. Since
solids are really only necessary for high RPM above 7000 and since a max
wedge never sees that it works fine. I have now well over 30,000 miles on
it. I had a 426 hemi in the 70s on the street in a 63 Dodge post car. It was
a 68 Charger engine that had been discarded by the previous owners due to
high mainenance and also the car had been wrecked. I did not have trouble
with it either although I did look after it. I drove it on the street for a
year but no one would play so I made it into a racecar and eventually
reinstalled it in a 69 Dart. It is still running BTWand is now in a FED with
an underdriven blower on it.(I was privilaged to be the ladst to freshen it
and it was still in good condition. It was high maintenance engine but not
unreasonably. I am currently helping a frend do a 426 hemi for a 68 RR. I am
in charge of parts picking and such and do it in conjunction with my old
friend and the guy i apprenticed for machine shop under Harry Wilson. It
will be hydrualic cammed , twin carters (or eddys) just under 10 to 1
compression and will need to be maintainace free. In my career the vast
magority of engines i built were for non car guys and would have to run with
competitive power for a season with no Don around as I didnt go racing wth
them. Steert engines were the same. Some fellows would not even be able to
change plugs so i got used to building this style of motor. Many are still
running 20 to 30 years later. I will see how this hemi turns out but I am
confident we can do it --- because we have to! The biggest deal with the 426
is getting the carb linkage in sync. The difference this makes is huge and
can be the difference between a puker (big bog) and a stomper despite its
seemingly simple operation. I know some go to the single four for the 426
but really once set up right it is a mechnical thing and can only be changed
by a well meaning but ill informed friend with ichy fingers. Now someone
will say you put a single 4 on your 426 MAX Wedge but wouldnt do so on the
hemi. I am defenceless to that because it is true. The 426 MW single four
was a factory piece though even though according to big Daddy museum it is
very rare. I almost had to bleed for mine. A simlar piece was remade by MP
a few years back though. For me the choice Hemi or MAX Wedge would be
strictly a $ thing. hemis are expensive, period, but they sure shut the
bowtie crowd up. You can hear them shaking in thier boots when they see one.
Anyway , you asked. That has been my experience.

BTW I loked after a fleet of 426 hemis for car collectorglen Cole for 23
years hehad everything froma 67 426 Charger to a 71 426 Charger including a
69 436 hemi 500 (flush grill and flush rear window. )That was sold to me

Subject: Hemi vs. Max Wedge
I know all you guys have good advice and opinions about things Mopar. So
let me ask a question as to your views on putting a 426 Hemi (425 horse,
dual quad type) vs. a 426 or 413 Max Wedge Stage III in a '64 Polara. I
know the torque and HP curves for them, but I am interested in the
streetability and driveability of these engine setups. I like to drive my
cars and don't like cars that won't start easily, idle dependably, or
stall frequently. And I like an engine that is dependable and not too
cantankerous and needing lots of attention. Given that, I would be
interested in your opinions of which would be best for a street car.
Thanks.
Mike in New Mexico
