I've been away from modding for about 2 years. I see people referencing new technology. What has really changed since the early years (1999-2000)?? Is there something I'm missing??

cam lobe technology

back in the day .525" was high lift, now .600+ is everyday reliable.

intake manifold technology....redesigned runners

cylinder heads!!
years ago the only way to get heads that flowed 300cfm+ was to have a hogged out runner in the 23Xcc range.

now you can get that same flow if not better with 205-215cc runners.

How has reliability increased?? .600 lift is still .600 lift?

Isn't the FAST intake the only redesign the provides gains over the LS6 intake?

What brand and style heads do you speak of?? Ported LS6's used to be the best??

Just trying to learn, and get with the times

there are several aftermarket castings

AFR, TrickFlow, Edlelbrock

not just ported factory castings.

and i'm also talking about how you can get ported stock castings in the 217-225cc runner size with 300+ cfm flow.
early on that flow was only found in 230+cc runner heads

So, Many more companies have put technology into the LS1's that pricing has got cheaper and the technology has been shared and learned so people can improve on each others designs while keeping it affordable.

So price has come down. Ok, but I still don't see the "Technology"? I was making 430 hP and 410 TQ in 2004, with a "mild" set up 224 cam 5.3 heads, and LS1 edit tune and all the bolt ons. There are some "new" cam and head packages not able to make that power? What's the norm for a cam and head combo now with the "new" technology?

Sounds more like refinement. Hardly anything "new" in terms of technology.

same **** new fancy names.... i mean seriously theres only so much you can do...

but the ls series motors themselves have evolved nicely with the ls3 and especially ls7 and thats probably where the "new" tech comes in, but its basically just better parts from the factory and a bit more displacement. probably nothing you couldnt do in 04, with the aftermarket but its nice to have that base from the factory.

I think more higher lift cams are common among cars now. Almost all of the Fbody guys I run around with up here in colorado around 12-30 pending on the track day. A lot of them over half are running big cams. The smallest cam in the group is a T-Rex cam, which is big IMO. Seven people are running "AIR CHAD CAM 235/239 .647 .610 109LSA" and going for "79 RWHP Gain, Cam Only" Link:http://www.coloradolsx.com/forum/vie...hp?f=23&t=1785

I agree it is more than anything refining technology more so than better technology. That is my .02

havnt heard anything about this? is it using and efilive switched tune or something?

Great thread . I have been away for about two years also ( just about the time the new AFR heads came out and TFS heads were just coming ).

What are the best heads now for a mild cam setup like a 220 224 581 584 114 XER grind or something similar. NA 5.7 build .

I am getting ready to move into another vette soon and want to start re educating myself here.

there is no "best head"

but for what you describe the AFR 205s would be hard to beat. although TFS is now coming out with a 205cc head as well. but nobody has them yet.

IMO for the Price and Flow and benefits of rasing your compression it is the PRC 2.5 Heads that Texas Speed Sells. I got them for right around 1000 bucks from my shop ordering them and getting them discounted from direct buying. They raise your stock compression to 10.75 to 1 and flow over 313 cfm. For the price you cant really beat that. Up here in Colorado a number of us are running these heads and huge cams and are all seeing over 450 hp on heads and cam, that is atleast more like 460-470 down at sea level with more air! Here is the link to the heads.

Yeah, new heads and new cam offerings, but nothing spectacular. I hear about new cams all the time, but in my opinion it seems like the "oldies but goodies" like the tr224 are still so proven that they are hard to look over.

"fancy names" That cracks me up. There are more whiz bang names for LS1camshafts than the 1960s ie. "half race" "full race" and I thought they were funny. Don't forget everyone now has a custom cam too, even though you can find an equivalent grind from one of the many cam manufacturers out there 90% of the time.

Fine tuning is closer to what we are seeing as the technology hasn't changed in years.

Perhaps more importantly have been the advances in tuning that allow more 'regular users' to utilize cams with greater durations, lift, and ramp rates than in years past 5-10 years.

You could argue that ramp rate has evolved the most. Cams can idle easier and 'ramp' up to high lift more explosively. I think I understand your point though. For all the 'new' technology perhaps 10-20 RWHP over the power curve has been accomplished (opinion) by cam alone. New technology does not necessarily always translate into better, unless as an user you know how to use it.

I am just waiting for valve spring technology to get to the point where you can put your new cam in and have those springs last 100k. May be dreaming.

Good discussion though.
