I've searched around online and found a few different specs that I'm considering and I'm curious what people's opinions are.

It's going in a 6spd car with a 376ci LS3 w/ stock heads and a D1SC. Biggest it will ever be is a 416ci w/ an F1C.

1. 232/242 .617/.617 117 LSA

2. 236/250 .613/.613 110.5 LSA

3. 232/244 .595/.612 118+2 LSA

4. 230/242 (?)/(?) 115+3 LSA

5. 220/234 .581/.598 117 LSA

I'd get someone like Pat G to spec you a cam. Best 25 bucks you'll spend. There's really no magic grind that will be optimum for a stock cubed LS3 and a stroker version of same. Kinda depends on what you're looking for manners wise too. Some like rough idle and lope and some don't. You can make big power with a cam with perfect manners that no one will notice or make a little more with a cam with "issues" that no one can ignore. Your choice. For a stock cube LS3, I like low 220's on the intake, low 230's exhaust with a 115lsa. I've been smaller and larger.....that seems to be the sweet spot for me.

I don't mind the noise of the cam, infact, I'd actually like some sound and want to make sure the money is well spent and it makes some good power. I would like the car to still be as driveable as possible though since it sees everything from stop and go traffic to extended highway cruising at times.

If you keep the LSA in the 114/115 range, it will have a fairly aggressive idle. Some blower cams use really wide LSA's to limit overlap and calm down the low speed manners. I'd rather go a little milder on the duration and keep the LSA a little tighter. Helps the bottom end. You're not in boost a huge percentage of the time. Doesn't make sense to me to spec a cam for all out power when you're not in boost most of the time you're behind the wheel. Let the s'charger make the power when you want it.

My answer depends on if this cam will be for now and you plan on changing it later or if your are getting it for the future now. I like the fifth choice the best.

I run a wide split on mine with a 116 LSA.

I would stick with the wider LSA's, like 117+. The LS3 heads will like more exhaust duration but I think 240's is too much. So I like #5.

$25 to Pat G.

Or call Champion and have them send you a cam.

#3 is in my car and it moves the mail pretty well on a blower that flows 200cfm less than a d1. Can't tell the car has a cam in it besides the fact that it has bullets on it.

230/246 .644/.652" 116LSA +2

Is what I'm running on my 427. Speced out by Pat G.

My installer just chose a 227/235 113+3 how aggressive do u think my idle will be n over all wat u think about those specs

Your results really have me leaning this way... I haven't seen many other cars that seemed to be more powerful than they 'should' be based on their mods, which makes it seem like that cam is making big power.

I would like to find something that is working in the real world vs. get one spec'd... Or at least have an idea about what is working best to discuss it with him.

[QUOTE=1sc334;1581006334]It will sound pretty mean. More than I'd want to deal with cam wise. Everyone's tastes differ when you're talking cams. Too much for me may be just right for you

Slo-Poc

I like five also, but he probably will not listen to people who beat him. Also did you put your exhaust back on bc it was really loud. Glad I only had to hear it for a sec. Till next year

Also pick one for the 376 then another for your 416. What's another 300 bucks at that point.

Beware that Mark's cam is in a 400+ cid motor. It won't be as tame in a stock cube LS2/3.

turbotuner20v

Lol... I have no issue with anyone who beats me... I don't like cocky sh#t talkers who think they are hossin the gas on the world with their 700 hp car.

Detoxx03

That's what I'll be doing. The cam I have now as you know is spec'd for this particular setup and when it's time to build a 416 I'll get one to fit that setup.

[QUOTE=old motorhead;1581006590]And as far as wat u were saying about making power down low n letting the blower do the work do u think this cam will do just that....and by the way i hope it does sound nasty cause thats wat i told them i wanted was something that sounded meaner than hell....like old school muscle :-)

Slo-Poc

Just joking big dog only friendly bantering... It gets rather boring seeing the same cars every year so why not talk up to make this fun the other 360 days of the year. Btw car def does not make 700. Trapped 134 in the heat.

Back on topic. I think the cam will wake that blower up.

what about this calculation:

{[(intake duration + ex duration) / 4 ] - lsa} *2

I've heard that you would want 0 to +8 on a blower car, which leaves only 3 of these cams in that range (assuming I have the specs on #2 right, I'm not sure if the LSA is correct since the specs aren't published):

1. 232/242 .617/.617 117 LSA (3* of overlap)

2. 236/250 .613/.613 110.5 LSA (22* of overlap)

3. 232/244 .595/.612 118+2 LSA (2* of overlap)

4. 230/242 115+3 (6* of overlap)

5. 220/234 .581/.598 117 LSA (-7* of overlap)
