EB 268 VS Stock cam shaft
Hey guys, was wondering who is running the eb 268 cam, i put one in my 87 4 runner, however the rpm range seems very narrow. I have heard some guys going back to the stock cam after putting in a aftermarket one. The engine seems to fall on its face after 3000 rpm, you guys runnig he 268 notice the same thing? Don't get me wrong, this thing runs great, just seems a bit lazy after 3000.
Thanks Doug
Thanks Doug

sounds like the RPM range it was designed intentionally to work at it's made for lower RPM torque (I think )
my 261 is happy from about 1500 to about 4500
my 261 is happy from about 1500 to about 4500

the 261* was designed for low end grunt...the 268* was designed for higher end (Ted himself told me this) so you have something wrong lol
my 261* is good up until about 4500 as well LOL!!!! it's a nice cam

I love my 261 from EB. I spent a bunch of time on the phone with Ted, and he pointed me towards this instead of the other one. In combination with his Street RV head, I'm getting roughly 21 mpg city and closer to 25ish highway (haven't done too much of that yet) but, on the large hills outside of Salt Lake, I hardly ever need to get out of 4th on the LONG (15 mile) climbs. You seem to get the best performance from this with -7* timing. Also, with about 650 lbs in the bed of my runner, it still out accelerates a few of the other stock 22re's in the area

Well thanks for the replies, i think i figured out some of my problem, turns out that i was'nt getting any mechnical advance. So after getting that working, the truck runs much better. Sounds like most of you guys are running the 261 over the 268, its sounds like its a better cam from off idle.
Thanks again, Doug
Thanks again, Doug

WTH do you mean "look bigger"...???
and that's VERY interesting with the cams there Gnarly...i still don't know why Ted told me that the 268* was better at high RPM than the 261*...and the 270* was even higher..lol..kinda weird

Also to add, My 268 performs flawlessly and i have no problems with it. My truck pulls better on the highway and has plenty of off line grunt. The major difference is when installing a cam like the 268 or 261 it needs to work well with a combination of other upgrades like exhaust and intake along with oversized valves and although marginal a better flowing head such as the lcengineering or rv head. I have all of these and can honestly say my truck runs like a champ.

am am thinking of trying the 261 as this thing dont seem to have any balls whatsoever 1500-2000 rpm. could be a gearing problem (4:10's w 31's) or could be because I had the block shaved 10 thousands and its a cam timing issue. (no adj cam gear)

7/9 is what ted told me as well. I on the other hand, have mine at .008 intake and .010 exhaust. I know not much difference but i tried both and the factory spec and this is the one that gave me the best results on idle and performance. When set at .008 and .012 the cam rattled pretty good so i toyed with it and ended up there.

I have the new cc252, I bought more for an updated design and fuel economy and was afraid of going over the line as no cam Comp has is for the 22re. I have to say the truck runs good and it's not like there a significant difference in hp. I tried 12/12 to break in, then 10/10 as per specs but the intakes were noisy, then 8/10, and finally 8/12 for now- feel better torque on the highway.

Just to clear things up about the intake and exhaust adjustment of the 268 as for how it works well here is how I see it or better yet feel it at 3200 miles since rebuild.
SET UP
268 cam Paired with a L.C.Engineering Pro Street head with the over sized valves and stiffer springs , tri y header from DOWNEY OFF ROAD , block bored 20 over , 82 SUPRA AFM , 5.29 gears and 5 speed with a MARLIN CRAWLER 1200 lb clutch kit and 35 x 12.5 x 15 KM's
ON THE ROAD
If you ever had people pass you and look at you like why are you on the road then you will love this set up.
I have people constantly looking in their rear views and moving out of the way and no I don't tailgate or ride their bumpers I just hold a steady pace with them and they seem to be shocked that a lifted 4runner like mine can keep pace with them at 65-80 mph and roll in the fast lane.
I can pretty much go where I want to on the road and at most any speed up to 90 mph for sure , never tried to go faster then that and it never misses a beat and will tack up to 5400 pulling all the way.
OFF ROAD
This set up works as well off road as on road , the bottom end grunt that it has is nothing less then IMPRESSIVE. There is not one point where there is a drop off or hesitation from off idle to full throttle when needed on hills it is hard to find a weak link in the power bandband. It flows so nice and you hardly even notice any shifts in power between gear shifts and harder yet to find anything to slow you down or stop you , including pulling out other trucks or heeps.
MY OVER ALL IMPRESSIONS
The 268 cam from ENGNBLDR has everything you need top end wise for on road daily drivers with oversized tires to the bottom end grunt for oversized set up off road and not a single point where you will be disipointed through the powerband on either side of the spectrum.
If you have the means and time to build a motor set up similar DO IT.
One thing I would say is if I had it to do over I would go with the ENGNBLDR head set up. LCE and ENGNBLDRs heads are so close in specs that it is really not an issue but $1049 L.C.E. and an extra $100 for 268 once you relize the cam that comes with it really is not much help until you hit 3000 rpm with it vs $558 ENGNBLDR for the head and cam combo makes a big difference and can lead to more parts when rebuilding or keeping your budget in check.
