lift: .237 int
.247 exh
duration: 244 int
256 exh
lobe center:104 int
111 exh
there is a dyno list somewhere here where(iirc) the lopo cam has all its torque at around 3 grand,and the horsepower tops out at around 4500.[URL="http://www.cardomain.com/ride/3358314"] -
o.k. thanks man, Im learning about cams so the lobe center is mild but the duration is decent but the lift sucks right? the H.O. is .444 on I and E right?Originally posted by ironstealth View Post
I was just curious if the lopo cam is a good torque cam and the heads and compresion is holding it back, Just curious if it is worthwhile for anything other than a paper weight?Comment

its a great torquer cam but its just done with by 4500 or so, no matter what heads you have. Better heads help it a huge amount, but its a torque curve more suited to a pickup truck or towing than a real performance vehicle. If you upgrade the heads, and leave the stock cam and gears you'll have a nice economical highway cruiser but its not going to be a screamer.86 Lincoln Town Car (Galactica).

Thank you sir, thats the info I was looking for, I figure lopo motors are a dime a dozen and lots of time you can find them relativley unabused due to being in townies and GM, crown vics, I thought that a lopo motor would be decent for like a halfton truck or something along those lines, I figured if the cam was good for torque wich it seems to be if you threw a lopo in a truck with a four bbl and some headers it wouldnt be such a bad lil unit.Originally posted by gadget73 View Post
oh and btw whats the differnce between lopo cam and explorer cam? similar power band or is it the valve float that usally holds the explorer back?Comment

so thats-
lopo- 244/246 .379/.395 with 1.6 rocker
HO- 276/266 .444/.444 with 1.6 rocker
imho the lopo cam is tiny, and leaves alot of room for improvement

yeah, its tiny. They actually used it on 92-93 pickup trucks. 94+ got the Explorer cam, which is much more lively, though its still not what anyone would call a big cam. Similar power band, with more top end and midrange power. The Explorer cam with good valve springs will pull maybe 5000 rpm, and then it kind of quits. The Explorer valve springs usually give up a bit under 5000 though. I've had my car up at 5200, and at that speed its making a lot of noise and not much else. Its happy with a WOT shift at 4800.86 Lincoln Town Car (Galactica).
