What cam after a EV27
Dennis de Vreede
of hopping up the '96 dyna a step further. Currently I run:
Mikuni HSR42 (great carb!!) - SE air cleaner
Compu-fire single fire ignition (rev limit 6000) with Crane coils
2-in-2 supertrapp with closed cap/18 discs
EV27 (crane time savers)
Screemin' chicken valve springs and collars (lift OK to 0.550)
heads ported
heads shaven 0.040 (raises CR to 9:1)
Just had the top end rebuild - was running bad and turned out one of the
barrels was out of round and losing compression (20K miles!!). Now 10 thou
overbore. During the rebuild I took the opportunity to shave the heads and
got them ported.
Just finished the break-in for the rings. Runs great - more power down low
(higher compression?) and come on real strong. Have the feeling the cam is
doing a great job in the midrange but running out of air at higher revs.
Fits the profile of a EV27 as far as I know. Had to retard the ignition some
3 degrees to stop the pinging - again the cam? To high of a static
compression? Valve train is making an unbelievable noise - can hear the
chattering even when wearing ear plugs!!
As mentioned I'm ready for a bigger cam - would like it to pull all the way
to the rev limiter (and running a little cooler AND getting rid of some of
this unbelieveable valve train noise)
ideas like the Ev46 - more overlap, should run higher revs but then I read
about these fast ramps (more noise??) Screemin' Eagle SE54 maybe? Or one of
the Crane cams?? Will not go to extreme - reliability is what one needs when
cruisin' through Australia - not many bike shops in the outback...

FWIW, my happiest friends have used Crane cams in their 80 inchers.
Provides plenty o pep, and are quieter than than the Andrews bump
sticks. Most decide on the 326. Good mid and top, without losing a lot
of bottom. I discovered the Trapp 2-2s don't workas well as the 2-1s. If
you go this route, try 18-21 baffles with an open end cap. Also, the
Crane hi-4 Ign allows for better fine tuning, and you might try
retarding the rear cylinder SLIGHTLY. Use of a Dyno is really handy for
this. As far as the pinging goes, try using better petrol, or an octane
booster may help. Have fun

Wires, Bosche Platinum Plugs, Ram Jett Intake Manifold, SE Slip-ons (retained
factory headers and crossover tube), EV46, and Andrews Chromoly adjustable rods.

The package is totally awesome, pulls hard from about 2500 to 6000. Freeway
speed acceleration is addicting and allows me to pass cages with a slight twist
of the wrist (which also invokes a shit-eating-grin and belly laugh every time I
do it). As far as noise goes, the motor sounds a bit different than before, but
isn't too noticable because the tone of the exhaust is so much sweeter than
before - it just doesn't matter!
The bike definitely prefers being ridden in the 3000-4000rpm range while
twisting through mountain roads and the power is instantaneous with the EV46.
Open it up to the limit and you need a seatbelt to keep your ass on the seat! I
ran with the stock cam, rods, and other mods for about 5000 miles before adding
the EV46 and rods. That was 500 miles ago and my bike has never run better.
Just when you think you can't love your bike anymore, you do these simple mods
and she's a totally new experience!

comes in at slightly higher revs and pulls to higher revs. I like it
because the idle is typically unchanged from stock. You will still
experience some valve train noise however, but I feel that's the nature
of the beast with a steeper cam profile. The EV-46 produces higher
static pressure and has great top end muscle. Make sure you have
chrome-moly pushrods as aluminum is said to be louder (but lighter) and
may flex under very hard use.
For the type of riding I do, I would prefer the EV-27 over the EV-3
I currently have (the -27 wasn't out when I was doing my motor work).
Wanna swap?

I've run an EV5 in my softail since 91, and been happy with it. Lots more
power in the mid-range, and you don't have to run the "red-line" RPMs to feel
the power. I did change the rem limiter to 6250 though. Only slight
complaint being the increased vibration, and the problems that that caused
(ie: speedo housing cracking and breaking, needing the "large" bottle of
locktite, etc.)

On the octane - down here the best one can get is 92 octane (leaded - that's
when you get the good stuff) - combined with near 100 degrees and the hills
around here pinging is almost normal. I retarded this time as it kept on
pinging through the entire power band.
Tried the trapps with open end caps - that's a bit much in the sound
department. OK for an hour or so but after a days ride the ears start
ringing - even with ear plugs...
thanks!

tappets
with this cam,maybe a jims big roller will work.
The EV 38 is a great cam,softer ramps so quieter.or the crane 310-2
If you want to ride on top take a Red Shift cam they are the best ,no big
tdc lifts so easy
set up,thought trough ramps wich are easy on the tappets.

The EV27 is a little too mellow once you bump the compression IMHO.
For a light bike like yours, the EV46 is a great choice.
The EV51 has a little more lift (.510) and would work real
good also. The Crane 326 would be another good choice.
