Default Quick question on LE "306" vs CC306

Well got a cam spec'd for the motor I'm getting

230/244 .598/.608 110 LSA 286/300 adv duration

vs the CC306

230/244 541/.573 112 LSA 290/307 adv duration

What will the differences be between these two? I'm learning with the whole cam thing but I told him I didn't want it bleeding out compression and guess that cam he spec'd will stop that??? that and what is going to vary from a 110 LSA from a 112???

Looks like the first cam is listed with aftermarket rockers. The 306 cam specs are right, but its on a 1.5 ratio.

oh ok, just making sure you weren't going to try to run a cam over .600 lift on those springs.

Nah lol plan on changing cam springs and head gaskets and a serious tune see how much I can improve the times. You know if he spun the motor up like the cam needed guy who has it says he only shifted at 6k

The LE would be my choice if it was between those two. It has a little faster ramp rates which will help in not "bleeding" down compression. But with most cams you lose Dynamic compression down low to gain it up higher. The 110 lsa is gonna make it pull hard through the mid and higher rpms much faster than the 112 lsa. The tighter lsa of the LE will hurt the nitrous just a tad compared to the CC306. Nothing to worry about but it still does.

The LE will be a little choppier but will also be a little more crisp.

Lloyd picks his lobes and event timing for specific reasons.
I see no reason to pick something generic when the man is offering you custom service for free.
If the 306 was the best choice, that's what he would have told you to buy.

As for my thoughts on the 306, it's an old grind with old lobes.
It does put down impressive peak numbers, which are useful for bragging and bench racing ... that's about it.

Here's some reading on LSA; they do a good job explaining what impact you can expect.

The cams listed on his site are examples that fit popular setups.
For the same price, he'll spec you a cam that fits your specific needs.

He told me thats for my set up and what im trying to do said that due to the event timing the compression will not bleed out and won't result in power loss. that and upped Lift numbers and different LSA should change it from the "CC306"

There will not be any sort of significant power difference between the two.

Well not looking for some huge jump in power....The cam Llyod spec'd doesn't bleed out compression which if you bleed out compression you lose power. I figured pairing the cam with bumped up compression there will be some nice gains......Motors out why not do it while its out kinda thing ya know
