I've been thinking about a cam only (with bolt on's in sig) and have many questions but mainly about lsa. One thing I do want in a cam is a good lope. I was wondering how many of you run which one and why. It seems from what I've read the 112 gives more power down lower in the rpm band. I know there is always a lot of talk about the G5X3 but I'm not sure if I want this big of a cam or not. Three things I'm really looking for, 1. Good lope 2. Power down low 3. RWHP at least 400 after tune. Any of you wish you'd gotten a different lsa than you did?? Open to suggestions also on cam size. Thanks

I dont think you'll see much of a difference that will make you not like one vs the other. Unless you have valve to piston contact! lol

Good lope and 400 rwhp can be used in the same sentence but I don't think power down low will be part of it. As a rule a smaller LSA will shift the peak power to a lower RPM but only by a few hundred RPM. When it comes to cams if you want power up top, it comes at the expense of power on the bottom.

Yep, you need to decide what you want and where you want it. I went with a cam that has an LSA of 115 so it doesn't lope much at all, which is what I wanted. The cam also has 5* advance to push the power into the lower RPM range. I am very happy with it, but it may not be for you. David Vizard wrote a very good book on cams and small block valve trains, you might want to pick it up and read it as he goes through all the variables. I found it very helpful, although at the time I read it I had already installed my cam.

Any more opinions or comments from anyone???

Since you already have the 4.10s I'd say the G5X3 will be fine on your car. If you planning to running the stock heads, go with the 112LSA for more lope and just a bit more power down low.(Not much, just a few hundred RPM)

Any more with cam's out there with any opinions????

Go for a 224* 0.580" 112* cam. great all around cam with a distinct lope especially if the cats are removed, beware the noise.
Expect 360 RWHP without heads.
If you go with a cam with more overlap, you may approach the 400RWHP mark but you'll hate the cam after the thrill wears off. Big loss of low end.

This link will answer all your questions from knowledgeable people.

Hope this helps, Curt

I love my comp cam 114 LSA with 581/581, though and if I give up anything down low I do not mind as when the power kicks in it is just awesome, oh I run without cats and oh I do have a blower to assist with Sick HP

If you want a lope than this cam is not the one for you as it idles close to stock

Cant complain about mine 244 248, 61x 61x 114 LSA

Try running that in a 346.

Darkness

No thanks. But some here have them with speed density tunning.

NeverT00Fast

That's tiny for a 408. I'm already running 237/242 603/609 on my little 346.

My previous car ('02 SS) had a 242/250 .612/.612 109 LSA in a 346 head/cam setup Still ran a Maf and O2 sensors and was 100% streetable!

Topic on hand, there are a lot of options available these days. Best bet would be to look at some dyno graphs posted on the forums and call up some vendors to talk to them about your specific goals.

I have a "Reverse split" cam in my 99FRC specs are 230/224 575/563 111LSA. I have not Dyno tuned the set up yet for max HP, just a set of the pants tune. I have Dyno'd at 379RWHP and 360RWTQ. I believe with a dyno tune I can hit 400WHP. You should not get caught up in dyno numbers, what matters is real world performance.

Anyways, I have the stock mufflers mated to LT headers and after market Cats. The idle to me is Great, slight lope in the exhaust and a little shake in the engine. Reminds me of an old style BB engine, just more quite. My HP is linear thru 6200RPM and starts to fall off at 6700RPM. Torque is a different story. Starts off at about 305 stays there until 3000RPM the rises to peak of 360 at 3750RPM. It is really cool to be low in the rpms and mash it and know that the cam will be coming on in a second, then feeling the Torque difference.

Well ther is my .02 hope it helps.

I went with a 228/232 114 set at 113. Good lope, idles at 800, plenty of low end power and very slight drop in fuel mileage. I do have a 3500 stall so there is no time at full throtle that the engine is not up in its power band.

See my sig. Absolutely love it and it screams on the track. Tony Mamo of AFR tested this cam extensively with his heads (114 lsa). So if you plan on eventually adding his amazing heads in the future, consider this cam on a 112 lsa. Check out AFR's website and talk to a tuner to see what they have done in the past to get the results you are looking for.

Amazing rwhp number there!!! That's the most I can remember seeing from that setup.
