if not yet but soon i decide to get an le2 setup how much better is it to use the le2 cam along with it? i already bought a lt4 cam and i dont know if i should sell it or keep it if i get le2 heads, how much more hp and rwhp / trq would i get from the le2 cam instead of the hotcam?
thanks

You would be better off getting the LE2 cam than the Hot Cam. The LE1 cam is a little better than the Hot Cam, so I would imagine that the LE2 is even better. BTW I have the LE1 cam and heads

DiabloGT

is it worth the extra money to go le3 or no? and should i just sell my hotcam or no? for how much?

DiabloGT

can anyone answer? and can they pass emissions?

Out of the cams listed, the Hotcam is the only one likely to pass emissions.

Hotcam will pass emmissions and if he grinds the LE1 cam on a tighter LSA it will pass. the LE2 will make alot more power, atleast 40rwhp more than the Hotcam.

The LE3 cam probably would barely run in a 350. If you are talking about the heads, not i wouldn't say it's worth the extra $200 for the extra 5CFM flow. The LE2 setup is good for 400-420rwhp.

Do you mean tighter as in numerically smaller?

I love my LE2 Cam and wouldnt trade it for anything! If you have LE2 Heads already I would go for the LE2 Cam. It kind of depends what your going for too. If you have stock lifters and stock springs hotcam might be better. If you have the hydrolic roller lifters and something like the big bee hive springs you can set your RPM's from 5500 to about 6800 or so and thats where the LE2 Cam makes some serious power. Its as streetable as the hotcam and it sounds way better.

can it pass smog emissions?

ShawnMacAnanny

I didnt mean tighter. I meant like from 109 LSA, to like 114 LSA or something. not tighter. Wasnt thinking cleary. I meant wider.

No the LE2 will not pass smog.

Guys,

You want to check the other post on the LE cams to see about emissions.

As for what works the best with what you have..... Well I would ask Lloyd first.

I designed these cams for what guys want. Personally a LE2 cam is a kick *** cam, it has low end TQ so with tuning it's driveable (in a M6 with 3.73 or 4.10's it's a baby, a A4 can have 3.23's or 3.42's but I would say 3.42's or more are better) it makes awesome power, doesn't have to go to the moon to make power and it has a pretty nice idle too!

I would say about 85% of the guys out there looking at Lloyds kits the LE2 is the cam for them.

If you have a 3500-4000 stall, 4.10 or higher gears, spin the motor to 7,000 and want to drag race.... A LE3 is a better cam for you. If you want a setup that goes to 6000-6200 max, have a stock stall and don't want to go crazy on the springs and valvetrain than a LE1 cam is for you.

The only other choice is how good you want the heads to flow! A LE3 head with a LE2 cam is one hell of a deal!

Good information I didnt know. I though the LE2 was like the CC306, but it seems a bit milder. Emissions I think is passible on 114LSA's from 227/233 and down.

More information you didn't know...............

All depends on what you mean as mild. The cam is actually a lot more aggressive in most measures. 10 more deg of duration @ .200 lift (no disclosure on the other measures of duration), more overlap, more lift and most importantly more power. (The CC-306 in the best case scenerio is down about 2% average power and 15hp at peak. )

The LE2 is also more balanced in dynamic valve area. Which is basically a measure of the lobe area and curtain area of the intake and exhaust valves. It's a better way to compare a cam to the E/I ratio. The CC-306 is about a 83.7% E/I ratio in that measure on a LE2 head while the LE2 is about 80.4%. Yes a ratio around 75% is supposedly ideal and is a old rule (from Taylor at MIT) but a higher ratio can also raise the HP curve after HP peak, flattening it out so higher RPM shift points help the average power. Too much for a motor can cause a loss in mid range TQ.

A 227/233 on a 114LSA has 2 deg of postitive overlap at .050 which can be iffy in emissions testing. The 227 and 233 lobes are old designs that have bad valve control in high RPM instances so they are probably better to stay away from.
