Why would TPIS put all their money into testing a single pattern cam for the LT1? I dont like how the hotcam sounds. I would pull the car to about 6100-6200 RPM's, and I would like a nice choppy idle. Sounds like the cc306 is too big, and you dont like the ZZ409. What bigger cam has better lowend/midrange than the ZZ409, keeping in mind i dont want a small cam like the hotcam.

 

The Hotcam works great with stock heads, and people say the "zz409" is too big for stock heads, or is not a good idea because of the lt1's poor exhaust flow, then why are people reccomending you the cc306? That cam is way bigger than the zz409, so exhaust flow is still going to be bad on the lt1. Also the cc306 is a bit big for a lot of people, and I do not suggest it for everyday driving. Your better off with the cc305 or the hotcam for everyday driving...

 

TPiS invested all their time into single pattern camshafts, because if you note, their best heads they sell are the AFR/TPiS. These heads, which I have, work great with single pattern camshafts. They have gotten only the best results with these camshafts. There not going to make camshafts that make good power with other peoples heads, but with theirs. I am running the zzx cam (240/240 .595/.595 112). Sounds and runs great. If you want something bigger than the zz409 but smaller than the cc306, check out comps xe grinds...or look into a possible custom grind..

 

Try the CC305, bigger than the hotcam, but more mild than the CC306...or something along the lines of the 224/230 offered by combo motorsports.

 

The reason that the cc306 will work better than the zz409 is due to the duration difference. The 409 is 226/226, the 306 is 230/244. Note the long exhaust duration. That is why it will work better for evacuating the cylinder.

 

The Hot cam is not a good comparisson for the ZZ409 cam the 409 is MUCH bigger than the hot cam, the giveaway is the lift with given duration, very steep ramps quick opening and closing. The Hott cam has to have 1.6s to acheive the lift whereas the 409 has 1.5s to acheive 520 lift. The downside to the 409 is the price 375 $ plus shipping for a cam is rediculous, when the Crane and CC are charging 240$ for their cams and 275$ for a billet one.

 

Are you kidding me? The Hotcam makes the same power as a ZZ409. Gezz, nice joke. I have personaly seen a ZZ409 on a stock bottom end LT1 make 434HP. The engine also had TPIS' heads, but no other mods to the engine. You're really hitting hard on TPIS, but what did you make with your 383 and your "special" heads and cam set up, like 400HP. Wow, huge numbers. It's funny how you're saying the ZZ409 isn't a good cam but it almost makes as much power with heads as your 383 with it's magical heads and cam setup.

 

I agree with the other comments. Don't use a single-pattern cam on the stock heads.

The CC306 is a little much cam for the average person, but those people are called "pussies."



I'd say at least a 3200 stall with that cam.

BTW:
434 Horsepower w/Heads/Cam is far from impressive. 434 rwhp with Heads/Cam is quite impressive.

Ill throw my .02 in here too. You guys have to compare apples to apples, the hot cam is the smallest least intense one of the bunch, the ZZ409 is probably not the best choice either with its high cost and single pattern. The ZZ409 is a better choice than the hot cam as the intensity is much higher than the HOT cam. The LT1 heads do have a poor exhaust port and benift from a dual pattern cam, heavy on the exhaust side. The 306 isnt the answer either, its plenty big and is pretty soft down low, especally with stock heads, a redeming factor is that it is a split pattern cam, that helps. If you were going to daily drive it I would reccomed a Comp extreme energy cam, or the CC305, split duration, intensity is good. They still make decent power down low, and you dont have to spin it to the moon.

I have used every one of the cams above, the HOT cam car makes ~420 @ the wheels on a 350, completly stock with the exception of the cam kit, headers (long tubes), a Moroso cold air. Stock cat back, TB etc.
I have done a CC306 in a firebird, stock heads, long tubes, 52mmTB, pullies, cold air etc that made 355 and has went 12.05 @ 113
I also built the 383 that TQdriven is driving........

 

The 409 is a single pattern camshaft yes, but has had very good success in next to stock LT1's, hell guys run them in stock L98's without complaint. The combo that you plan on running will produce about 400hp at the crank with the 409...If you are planning on running N20, forced induction ect, i would suggest a duel pattern camshaft, but with a 409 in a NA motor will work very well. It is the middle of the road camshaft.

The unfortunate truth is that Peak HP sells camshafts...all people care about is that 6500rpm HP number. There is a lot more that needs to be considered than just that top end number. Ever drive a 460hp 350 on the street? It sucks! The 409 will provide the best low end drivability, both the Hotcam and CC306 will produce more power up top. Its all on how you want to use the car...street, or strip. I have a lot of experiance with the 409...it makes a great street camshaft, and does well at the strip, it kind of gives you the best of both worlds.

Thats my .02,

I love how you keep going on about the hotcam, which i CLEARLY stated i DO NOT WANT. I'm probably going to go with Coles suggestion and go with the ZZ409, power down low is very fun, im not going to be spinning the motor high all the time either. I've seen coles 1/4 times and they are wicked. Sounds like the 306 needs to be spun high and not much bottom end, question on the XE grinds tho, who runs a 227/233? How does that compare to the ZZ409? Where are they similar, where are they different? How do they compare soundwise at idle and on it? Thanks

 

If you guys want to argue, do it someplace other than here.

There's no place here for this kind of crap.

 

I say u need a flux compasiter! Lmao you guys crack me up

 

And you resurrected an 8 year old thread for this?
