High Torque Cams
if you want some great low mod tq, its not all the cam. Good heads, and compression.
Newera has done some good street tq cam cars, then added good heads and gain at all RPMs 30-40wtq ! good hp say 450whp, but then 430+ wtq. Compair that to average bolt on "tq" cam 228 whatever. you get 385/400, tq 370-380 setup. then adding a budget cnc ported head it makes 420-440 whp but the tq is 390-400. Were good heads are were the TQ is with the same cam.
Its not all the cam you need to talk about, and have these thread go on, and on for pages. Picking out a custom cam in dur. @ 05 differences 1-4*. Your not going find a difference of 15-20 wtq in that. I bet a good running SBE with great heads and bolt ons, will make within 10 numbers on any 224-228* int 228-232* ext .590-.630 lifts.
Its not cheap, but Ggod heads and compression are were its at, then any cam will be a hero then.

I looked, and don't think I posted this car with this SSHT cam on here. I did on a local site, this was back in 2007 when I was working at newera. I think this was winter time,too and we had some time. To do this same day, right on the dyno. (I think the base was the day before) But it was all at the same time. I think the fast92 just came out too.
This is with The streetsweeper HT (228/232) cam and ET 215 CC heads with an unported FAST 92 intake , the choker is that it has SLP headers with cats but it is a well matched street combo , the below graph shows when we dynoed it stock (with borla exhaust) and then added the SSHT cam with full bolt ons , then when we added the ET 215 cc heads with the FAST 92 intake.

I know thats not what this thread is looking at cam/street wise. But I hear from alot of people that think a smaller cam will make more tq, and when you got bigger you lose tq. And you have to rev it more to make more power, but the cam will have less tq. Thats not always true, Big cams make big power AND big (high) tq. A big cam is not for everyone thats for sure. And the "low" rpm some people want to use is all over, I think under 5K is the low end of my car haha
But some try to look at 2,500-3,500 range, nothing wrong with that I guess. But I think the cars not setup right if you looking "big" tq, for h/c setup in that range, and your tiring to slice atoms with a hatchet. ( haha I donno there some old saying out there like that)

Like studderin mentioned, good heads and compression are your best friends.
Here's my graph. See for yourself.

While it's true a lot of camshaft designers tend to concentrate only on using the latest and greatest catalog lobes to stay current, the entire valvetrain "package" is what must be properly matched to the application or all hell breaks loose.
Even if the plan is to use the most aggressive lobes available, the ones you would assume will destroy valve spring life, they can survive if the correct peripherals are used with the profile. Bottom line - there is a big difference between a price point cam kit and one which is designed to perfectly match the application.
The SSHT noted in Johnnie's post is a well proven piece. As a matter of fact, it works so well that there have been a lot of people attempting to copy it but because these aren't catalog lobes, they can only attempt to do it.
If Johnnie wants to share, the boys at New Era have done a lot of testing and in every case, the clones to the SSHT, the original StreetSweeper and even the Hellion have fallen short in both peak and average power numbers to the real McCoys. Mike and crew are very thorough when they are doing the R&D so I have faith in the results.
For sure its all in the combo. Lighter valve train, better quality springs, proper pre-loads.
I am for sure interested in your HT cam, and I would not buy a knock-off. The powerband is perfect for where I want to be.
That hellraiser cam looks MEAN!
I am going to be shaving my heads, running a thin cometic for quench... would you still recommend the streetsweeper? Or is that hellraiser better? PTV with shaved heads and gaskets?

Any cam can kill springs if it isn't set up properly. Heavy wall pushrods, shimming to within .050 of coil bind, checking proper install height, going with the springs the person selecting the cam tells you to... Things like that.
I wouldn't consider my cam a "TQ Cam" but I'm damn proud of my numbers. I attribute a lot if that to the AFR's.

Drivetrain loss for the V1 is significant. They always dyno lower than GTOs, which themselves dyno lower than Vettes and F-bodies.
Hmmmmm
So many dam choices and variables! If you want the tq... Smaller cc intake runner and higher compression for sure...
Ed's streetsweeper HT
Texas speed PRC stage 2.5 5.3 heads (not ls6 so it will have a smaller cc without being decked = more ptv clearance?)
Their upgraded spring package for the extra 50 bucks for 0.675" springs
Cometic 0.041 MLS increase quench
Which pushrods? Hardened comp eng?
Deck head 0.0?? For around 11-11.5:1 compression
5.3L flat top bottom end L33
What's the DCR in that?
Run M6 trans... Alum fly... 390 or 410 gears in a C5.... Win? Or am I off in something...

Yeah... I was afraid this question might be like the chicken or the egg! haha
There are sooooo many variables that come into play with power in general.
I'm mainly just wanting a street friendly cam, not necessarily a driver friendly, but something that will really roast the tires.
I've narrowed it down to a few so far, which you guys have helped with immensely.
Thanks!

I made 452/418 with a 224/228 .595/.595 110+0 LSA. using TEA 5.3 heads milled down to 59CC chambers which give it 11.4 to 1 compression. 375 RWTQ @ 3200 rpms means great throttle response to say the least. With those small intake runners you keep your intake velocity nice and high. The heads flow 316 on the intake side. Valve springs last 50,000 miles. This combo works well for me. Nuff said.
