Thoughts? Time for a bigger cam... Time to upgrade the goods! 
Currently have a custom PatG spec'd cam (219/227 .600ish lift) made specifically for the STOCK torque converter. It did an excellent job at what is was designed to do, as it gained power literally everywhere and picked up 45rwhp and 26lbtq.
Two months down the road and I've purchased a 3600 stall and am in the market for a bigger cam (I initially thought I'd be done modding after the cam...riiiight
).
After talking to multiple members, sponsors, etc, I think I've decided to go with something along the lines of a custom 228/232 .600ish lift 111-113 lsa (hasn't been spec'd yet so I'm not positive on the details exactly).
Just wondering what your thoughts are? I think it's a great power/price ratio considering I'll be able to keep my hardened 7.425 pushrods and basically new Comp 918 springs (only 1k miles w/ supposedly new design that is good for .625 lift, but who knows).
With the 3600 stall I figure this seems to be a fairly good setup for a daily driver that likes to run whenever given the chance. As always, I think there are a lot of knowledgeable people on this forum, and I'm absolutely open to opinions/comments.

I like the TSP 228R, good power under the curve and smooth idle with the 114 lsa. If you want the choppy idle 112 lsa or lower. Also the TR230 is nice for dd power and streetability.

That's why I'm opting for something that is still very streetable with the right tune and my setup (3.73s, 3600 stall), and will be a worthwhlie gain for the money of a new cam.
Anybody else have thoughts on a different set of cam specs?

Actually, the cam I have now was made by Geoff at EPS using the lobes you mentioned. The high-rpm stability, good power, and reduced stress on the valvesprings made them an appealing choice.

For the hp gains, the price/gain ratio is fantastic. Heads might have to wait a while.

It's on a 115+4, but still has a decent chop at idle (surprised me actually), since the idle speed was kept low (550rpms). I'd like the new cam to make it worth my while to swap, maybe 20-25hp? Does that seem unreasonable with the two cam choices I've mentioned?

Yes, I meant 226/234, as I suppose I'm not quite ready to go with a 300+ duration yet...

I'm not planning on the 226/234, that was just a suggestion I got yesterday. I'm going to look at a local set of 243s this weekend that are listed very reasonably. If they're in good enough shape, I'll pick them up and mill, get a decent vj, bowl blend, and port the runners. After getting the flow numbers I'll have a new cam spec'd.
I'm still wanting something that's going to produce a lot of area under the curve, generally the flatter the torque curve, the better. At the very least I'm leaning towards something around 228/232 .600ish lift 111-112.

I'll make my recommendation public..
230/238 110+2 on EPS lobes.
Remember you have to work with the comp 918's you have, and those would need to be shimmed for those lobes. Anything more aggressive like an XFI or LSL and you are going to have to upgrade to duals.

The XFI lobes were intended for the new 918 springs, I run them with my set-up...230/236 XFI 113+2 imo if you're milling the heads to bring static over 11:1 and the wider lsa will flatten the torque curve
