if you dont mind, what were the specs on the cam. seems like you had basically what i'm starting with. next spring i'll be adding a set of afr's 205 heads into the mix as well and possibly a fast 90/90 combo.
trying to get around the +450hp (streetable!) before i stroke it

dont get hung up on that 450 hp NUMBER. as it is only a number.
Many smaller cam cars are quicker with the right heads and other parts
They may not have the top end but will be rockets off the line or out of a corner.
Comes back to that other thread, Power under the curve or top end.
I have run lots of big cam LS1s and LS6s, smaller to small mid size cams are always quicker off the line, roll racing or out of corners then big cam LS1s or LS6s.
When you have more cubies that is a different story
Not eveyone runs a stall, some of us have manuals

I put down 452 rwhp and 408 rwtq with a 224/228 581/588 110 lsa with a 12 bolt rear that has 4.30 gears. I also have a fast 90/90 that has had the Mamo treatment. As for heads I have a set of stock 241 castings that have been ported and decked 30. with bigger valves. Since then I whent with a much bigger cam and had to flycut. The 224/228 cam is a great dual purpose cam that can bring it at the track and the street

It won't like any cam too much with 3.42's. Remember, pretty much any cam that really wakes the LS1 up steps your "power band" further up as well, which usually results in some loss down low and it will buck on you at highway speeds in 6th gear like a freak. You'll definitely want 4.10's, or at least 3.73's. That cam works great with stocks heads BTW.

with the AFRs you most likely would be in the mid 440-450 range.
I would say with full bolts ons and 5.3s and a good tune you should be in the 420rwhp range where as with the AFRs would be in the 430-435 range. However I think the AFRs would give you better hp throughout the rpm range and not just at peak.

What do you guys think the difference would be if i used a vrx3 (226/228) with the prc's instead of a 224/228 TECH Regular

Great project and Good Luck.
Let us know when you hit the track / strip .
What? AHHHH.... I completely disagree with that. I have had 3 LS1 cars and my 224/224 on a 114 wasnt nearly as peppy on the throttle response around 2600 rpms as my f14 futral cam. Now I will say this the TR224 cam was much better with drivabilty and to program but I love the power through my much loved 9" with my 3.89 gears. another thing is that the intakes make the biggest difference with that throttle response.
I think the 224/228 will be better for nitrous due to the extra 2 degrees on the exhaust side to scavenge everything out of the exhaust ports. Well as long as you have long tubes with that set-up. I put 224/224 with the stg 2.5 prcs on my brother's car and through his 4l60e I would be surprised if he records 430rwhp. That car is nasty too! Too bad I kill him off the line with my cam only suspension upgraded car with 3.89 through the 9" while he just spins

LS6 block, 243 heads that have been polished ( clean up inside ) not really ported.
921 springs with stock sodium LS6 valves
TPIS LTs, Random Tech High Flow cats and X pipe then straight pipes
my own CAI with a TPIS tb.

I think with a good tune and fast 90/90, if its through a manual and also depends on if you have true duals or single. Probably around 425 true duals expect 435, with the AFRS id expect atleast 445ish. With my 232/236 on a 112 cam I am going to say 455-460ish with prcs and maybe 5-10 more with the afrs
