Best undercurve cam?
I'd put some money down on that challenge too

I would bet that 218/224 .604/.609 113lsa+1 That Predator-Z spec'd for me...i'll bet
its got sick mid-range ( under the curve ) A cam doesn't need to be larger, plus larger cams
are more peaky an a 346cid motor. The cam above or the TR224 112lsa would be both nice.

I have a lot of respect for all of the 'challengers'..but IMO Predator-Z has a very unique understanding of cams and valve events.
Not hero worship, just vouching that for 'free' advice and non-conventional thinking..might listen to him.
Especially with stock heads and your driving requirements. If you are willing to mix up some lobes and understand the valve events, you might be able to get exactly want you are looking for.
Have fun. No cam war, just sharing my experience.

Just as stated right below my post...ask Predator-Z...i never asked him , but he saw my post about running a small high flowing head and that i have an A4 and plan on using a Vig.3200. And plus i'm a torque junky, Predator-Z knew with small runner heads like AFR 205's or PRC's Terminators or even ported LS1 or LS2 heads he came up, in my opinion, one of the coolest cams what will make just about the same amount of under the curve torque, and it will peak sooner making it one killer street or even a nice strip car, but you wont have to rev it to 6,800+ rpm....For a lower E.T. car at the track or from light to light on the street, making as much power, actually torque, early in the rpm band. A killer street setup usually is a setup at builds its power earlier and peaks alittle earlier. But i thank "Z" for his recommendation for my "street killer" setup. Good luck...Also Patrick G is darn good as well just so ya know, but good luck on your setup....and man i'm starting to LOVE the TFP 215's

Sounds like you want to keep your IVC around 40-42 degrees (or less), and EVO ~46.
Then you just determine how much overlap you can live with, and where you want to peak your HP at.
Blanco is right that tons of 224 cams have proven to be phenomenal on both the track and street.
Some of the 'bigger' cams really shine as you bump up the compression. If you wanted to try a 228, how about a 228/228 111+3. If I calculated correctly, IVC ~42, EVO ~48. Overlap 6 degrees, so more than the 224 series cam.
It is getting a little late, so if someone wants to double-check my math and valve event terminology, please do.
Many of the sponsors can elaborate, along with Mr. Patrick G. Texas Speed just did a ton of dyno work, and if you can spring for heads..you will never look back.
I'll give ya three different choices for stock heads, and let the cam experts comment:
1). 218/224 113+1 Overlap: -5
2). 224/224 112+2 Overlap: 0
3). 228/228 111+3 Overlap: 6
All have similar IVC's & EVO's. Like I said, double-check my figures..sometimes with differing lobes and ramps rates, it can change some of the valve event figures.
Hope I didn't make it overally confusing. Your question of "Best undercurve cam", will always attract a lot of interest and differing opinions.
Cam choice is fun. Hope you find it just as intriguing.
Good luck.

Here is a graph for the sceptic, non believers (you know I love you all) 
https://ls1tech.com/forums/attachmen...110lsadyno.jpg
and that is with XE lobes
, 224/224 .565/.565 110+4 LSA, cam only + bolt ons (the right bolt ons for the job)
405rwhp/406rwtq (corrected)
Remember guys, COMBO< COMBO< COMBO (total COMBO for task desired)
BTW (just to tease you), this was done way back in 2002/2003

what else besides a dyno tune and ls6 intake should I really be looking for to optimize the combo?

When you make a statement like "TR224" is the mother of all 224s and no one can do better, I only showed you that it is not quite so in reality. You have to realise that lobes have evolved.
That 224 XE has a ramp rate weaker than TR proprietary lobes on that 224. It makes more undercurve for the simple reason being that the VEs are right for the combo at hand.
You cannot just choose a lobe and say this will make the most. You have to decide on powerband desired,choose VEs, match lobes, look at various lifts, all of this while knowing exactly how the rest of the motor/drivetrain combo parameters will fit in.
What is a custom cam? surely you know that the cam is the last item that goes in a motor build not the way around.
The beauty of the variety of lobes and rates we are offered nowadays, is that it gives us more to play with than back when TR224 was designed.
Reality is it can be done, it has been done, I can do it too
Oh and just to set the record straight, that XE cam was not one of my creations, a member named DAPSUPRSLO ran it back then 02/03, it came to light way back in cam discussions (before LSK<XFI<LSL<LSr lobes were created).

Well lets see it in a real test. I'm not saying it cant be done, I just havent seen it proven yet.
Mixing and matching lobes is not new either ...LOL and guess what I've got an L92 cam here with mixed lobes as well. It was developed for an ls2 for a daily driver.
But lets see a side by side test as suggested. Not a dyno sheet from 3 years ago...LOL, you know that proves nothing at all. No disrespect intended.
Let see a tr224 112 lsa and your cam strapped into the same engine and post some results. Thunder developed that cam how long ago? It still rocks and has been mimicked by countless people a number of times. I guess thats the sincerest form of flattery.
