G5 or TR224 cam?

Not really sure. I've never heard Lou comment one way or the other on that topic. Was he talking about in the past, around the time the cam was introduced?

My heads exhaust flow is *excellent*. TEA gets the ports to flow quick for good torque right off the bat (intake is as well, but for right now, the exhaust seems to be the big difference in both cams, like I noted above), so I'm not so sure the extra exhaust duration (and lift) of the G5 is really buying me anything with my specific application, especially since I'm not gonna spray. Comments?
<strong>Bear, thanks for the reply. Which of the two do you feel was the 'stronger' of the two cams?
</strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">I ran better times with the G5. It was about .2 faster. I would not trade the time for the comfort. If it was .6 or so maybe I would, but not for that little more.
<strong>ON THE SPRAY, how much more rwhp and tq is the G5 going to make over the TR 224?</strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Anyone care to comment?
It does shake, nothing that I can complain about but enough to make it look and sound awsome.
Paul from Thunder said the best shift point would be at 6500 and setting the rev limiter at 6800.
We are getting 2 licenses of LS1Edit most likely this week and are hoping to be able to tweek at least 390-400 rwhp out of it. The number above also only reflect a 6250 rev limiter. We already picked up EFILive which is helping to find out everything possible before we start playing with the pcm.
Just expect to be hitting 100mph without trying and hitting the rev limiter all the freaking time. What a bummer huh??? <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
The G5 will have quite a bit more low end grunt over most cams. Its Road racing backround gives it that nature. I am staring at my graph, and I have ~370 tq@ 3200 rpms <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />
Crusing in 6th gear @ 70 mph is fun. No need to downshift, no lugging, no surge- just plain passing power. Sure, downshift to 3rd or 4th. But beware, youll shortly exceed a hundred <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

That's encouraging news. Is that graph posted anywhere, or would you mind to post it if it is not already?
Do you think the profile of the G5 will work good with the 5.3L heads? The TEA heads have excellent flow on both intake and exhaust. With the exhaust duration of the G5 being somewhat long, and the lift being relatively high, I am curious as to whether that will help me or hurt me in comparison to the single-pattern profile of the TR224. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> That's the real debate for me right now.
Thanks for all the replies guys, it's a killer thread!

TEA is Total Engine Airflow they are a board sponsor.>>>>>>>>>>>>over there>>>>>>>>>>>>>>>>>>>

TEA sells an excellent sets of LS1 Stage II heads with dual springs and lot's of good stuff. The heads flow very well and make excellent power. TEA is well worth checking out if your doing heads and cam etc. Call and ask for Brian Tooley.
My TEA heads and SRP cam should be installed soon.

If I understood Lou correctly, the cam was spec'd/designed after the head porting program was finalized (read: port flow for both the intake and exhaust ports was known). That way, the timing of the valve events compliments the flow characteristics of the heads. Makes sense to me.
Anyhoo, with that in mind, we can see why the G5 may not perform any better than "average" (for the size cam that it is) until it is used in conjunction with heads that exhibit the flow characteristics (whether they be from LG or someone else) for which it was designed.
To my knowledge (and I admit that I could easily be wrong), the TR cams were designed to be good "generic" or "rule of thumb" cams, with no particular porting program/port flow in mind. That could explain why we see the TR cams kicking *** with stock/GTP/TEA heads, but when it comes to complete heads/cam packages (such as those available from LG, MTI, ARE, MMS, etc...) that were designed to work together, the TR cams fall slightly behind.
Don't get me wrong, I'm not trying to bag on the TR cams at all (are you kidding me?? They produce EXCELLENT results both on the dyno and on the track!!), just trying to help others understand that it's not just about the raw parts involved, but about the package as a whole.
