Trying to figure out which cam for build
Cool. Did you run the time in your signature with that combo?

Back to cam suggestions LOL.
I would humbly submit the Cam Motion LS1 Titan 4, 227*/232* 113*+4* Adv.
as the ideal street/strip daily driver capable cam for your combination and
goals.
Good Luck

Yep, I have the BTR stage 2 which is similar and it's great for street driving.

So, I'd keep overlap at 6 degrees or less for a very streetable combo... I also have found a 45 IVC and 55 EVO makes the most usable power in a 346.
So, with those cam events and slightly biased intake overlap, I'd recommend a 229/237 113.5+3 combo. Using 370/362 lobes for .629/.615 lift numbers from TSP or Cam Motion.
It would make good power and drive great. I'd aim for 11.2:1-11.4:1 CR or so with it as well.

I'm really considering ditching the pb pulley now. I will look out for a blem ati 10% and if not just run the stock balance. I already got some 42# gtp injectors ready to go and will be doing the trunion bushing upgrade for the stock rockers. I am looking into the 11/32 prs just need to make sure they will fit in the prc 225s.
For compression I think they only make those heads in 62 and 68cc chambers so will probably have to go with the .041 gaskets. I also have a arp 12 point head balancer bolt ready to go and was planning on the ls2 trays as well.
I will look into a bigger lid and maf. What sizes would you suggest on those? 104 and 85? Unless Carl thinks I should go SD. I would definitely like to see your cammed cars manners this spring.

Sounds like you've got it down! I have the 104mm lid, I think it is pretty much the same as the 98mm with a lip at the back to put a MAF into. It sucks to fit a coupler over it, but a 4" exhaust pipe section fits in there pretty well. On the 90/92 setups I see a lot of people go with a 85mm MAF. Carl recommended I go with SD, let me know if he recommends otherwise for you.
also research the 100mm maf, you will find they really arent that necessary on a 346. by far the easiest route is the 98/85 maf combo. finding the reducing coupler to work connecting the 100 maf to the 90mm tb is a pain
before you let anyone talk you into speed density, please please research. there are a ton of threads on this that will hopefully help steer you to what is personally best for you. and dont let a tuner make this decision for you. tuners that cant do speed density will just tell you a maf is better anyway, and then the guys who dont wanna deal with the driveability portion of a 100mm maf tune will tell you to speed density. id recommend a tuner who is willing to do both for you.

Sure, the Stage 2 N/A (P/N SUM-8707) is 226/238 113 + 3, .600/.600. I/O 3 btdc, I/C 43 abdc, E/O 57 BBDC, E/C 3 atdc. 6 degrees overlap.
I'm thinking now that may be too big for a street cam unless the prc 225s are nice enough to make that cam behave like a smaller one. Can anyone confirm that? As stated the tuner is an excellent one so maybe he can make the tsunami drive street friendly.
