383 stroker, worth it?
my lil angry 346.. is just.. not big enough,
like i have mentioned in some posts here i want a big cube block, (LSX/408/402)
but its just to expensive to build another motor when i am not even finished building the 346,
thats why i started thinkin about buying a stroker kit, and some big cam like Trex/ms4/vindicator,
is it worth the 3k it would cost me? i should be around 420ish rwhp N/A on my current H/C/I set up, (stageII ls6's 59cc 226/226cam fast90/90 and more)

For me, low/mid range power outweighed the peak numbers.
I also wanted a combination that would be a decent daily driver, of course that is subjective too.

i got a 226/226 585 112LSA cam in my motor now,
the 420rwhp is around what i am making at the moment, and for me that is just not enough,
thas why i was thinking about a stroker kit,
isin't the ms4 big enough for a stroked motor? or should i go bigger?
what amount of cain could i expect?
thanks all

Last year I had been running the TR224/114 cam in my 383 with AFR 205 heads. I was putting down 425rwhp. It was fun...but I agree, it wasnt enough.
My winter project was to upgrade the cam. I called Tony Mamo with AFR, and he suggested their 234/238 cam, I choice to keep the 114lsa.
With an updated tune...well, you see my numbers. I'm happy with the setup now. Sure, I still could have gone with a larger cam, since my pistons already have reliefs in them, we even measured clearance, and I do have some to spare. I think my next project would be do get the heads milled.

you should get a cam that is designed for a bigger cubed motor, not just grab a popular big cam that's made as a max effort cam-only 346.
speed inc has quite a few stroker grinds. their SS2 cam is a very street friendly cam that has made impressive horsepower/tq.

part of the reason for i want to do this is that i want to reuse my patriot stageII ls6 heads, 59cc, they should be good with the stroker kit?
how much has to bore the cylinderblock for the 383 kit?

You are exactly correct. ( I think)
Actually, according to Cartek, even with the 3.905 hone, you are at 382ci with a 4" stroke? They have a 383 offering that is a larger bore and shirter stroke. (Does anyone know for sure?)
Either way, a 383/382 is a great 500whp package +/-. Killer midrange and top end too. My car had the worlds worse tune and did close to 500whp. Specs are in sig.

Like the above states, get a 383 built and cam/heads matched. If you got the dough for some nice heads and fast 90/90 port matched 500rwhp would be no prob and nothing to sneeze at. They are torque monsters too, I've always wanted a 383 on the other hand I am getting a 408 built right now
