500 to the wheels N/A Im thinking over the winter I may try to build another motor. Right now I have an LS6 Create with the Magic Stick 4 Cam.
With Stock 243s it made 424/370 to the wheels on DynoJet
Can I use the aluminum block to make 500+ to the wheels
I was thinking of a stroker kit and a .030 or .040 bore, and keep the cam and get a set of 243 patriot heads or the PRCs LS6s. Id like to up the compression a bit maybe also...idk.. Im looking for a bit more low end torque if possible with out swaping cams. Or should I have a custom cam something like the MS4? I love how it raps but Id like to be faster.. Im not building a race car just a weekend car that I can enjoy and still drive.
is this a good combo for all motor?
OR what is a good combo for the street..

You cant bore the AL block. It can only be honed .005-.010 depending on the year casting.
Unless you up the cubes its going to be hard hitting your goal with a stock casting head.
You're not going to hit 500rw without bumping up the compression.
The more power you make the faster the motor will rev. If you want more get an UD pulley, AL flywheel, and Carbon D/S.
Not trying to be a dick you have a lot of reading to do. You can start with the threads in yellow at the top of the forum.

Iron block with 4.03" bore.
(Or LS2 with 4" bore, or L92/LS3 with 4.065" bore)
4" stroke crank.
Forged pistons.
Forged 6.125 rods.
Get PatrickG to spec you a cam.
WCCH Stage II L92 heads.
LS3 intake or Victor Jr intake.
1 7/8" headers.
Pick an exhaust.

There were quite a few people that hit 480-500 RWHP back in 1999-2000 with AGGRESSIVE head/cam kits. Very aggressive though. I would think with the far better heads, intakes and TB's out today you can hit 500 RWHP or close and not have an engine that shakes your fillings out. Stroke it and it'll be done much easier.

With an LS1 engine unless you boost you are going to have a hard time getting to your HP mark. The only way to get there is boosting. It is easier to reach the 450 mark and you still need a good set up and a hell of a tune. Here is a thread that I put on another thread about LS1, honing, boosting stroking and hp

Im not too far away now..Im just wanting a bit more. Iv already got the Fast 90/90 1 7/8s long tubes, Moster Clutch kit with lightweigh flywheel, full bolt ons basicly..just want more now. I dont want to go with nitrous..
425 to the wheels now..Would a set of PRCs and fly cut the pistons do it, but while Im there..I might as wheel stroke the damn thing right..

stroke it
new pistons
new rod bolts
good heads
and port the FAST if its not already
there are a number of buys running 475rwhp with stock cubes, GREAT heads and the ms4 type cam.
with more cubes it should be very possible....if you DON'T make it...you'll be damn close

Whats a "good set of heads" Im not wanting to drop $2000 for just heads right now. Thats why I was looking at the PRC or Patriots..or have my ported...I could reuse my springs and crap..

I am pushing 450 rwhp through an A4 with an Ed Curtis cam and I had Advanced Flow Inductions CHD do my heads to cam specs. Since they do a lot of work for Ed I supplied the 243s, springs, valves and everything. Total cost to me $1085!

I think 500rwhp is possible with a 383 ls1 if you didnt want to get afr or tfs heads then i would send your to total engine airflow and have them ported or you could get tfs as cast heads. I would probebly have a custom cam made for your combo haveing a cam talor made for your combo would help get more hp and most likly driveabilty.

One thing that I don't understand is that you don't want to spend $2000 on a set of heads,but in the next breath your thinking that you might as well stroke the damn thing. If $2000 is more than you want to spend then doing a 383 stroker is way more than what your present budget will allow for. It appears that you need to do some serious research on the cost of stroking a 346 LS6 engine.

500rwhp will cost you a bunch of $$$$$$...
I would go with a nice set of heads(maybe TFS for +-1600$) livernois, LS6 2.5, a badass cam and ported FAST 92mm. This done, you wont be at 500 mark without a nice full flowing exhaust and electric waterpump, UDs and spot on tune!
Better pray for it, and hope you dont get on a non-friendly dyno...
The cheapest way to get a stroked LSx is getting an iron 408 these days. But it wont get you to 500rwhp if you dont match heads/cam/exhaust...
*I re-read your post and see youre already at 424 which is very good with stock heads. I would just go for a cnc program on your head or a ported FAST 92mm. Heads beeing the complicated choice and the FAST the easiest part to slap on, but will not give you best results. And the intake doesnt require fly cutting too but a retune is required..
Have you gone to the track yet?

No Havent had a chance to go to the track..Its rained for almost 3 weeks straight. Im going this weekend.
I would think I should see 11.90s to 12.0s @ 114-118 if I can get it to hook up on DRs in a full weight car. Wish I had some 15 or 16 inch wheels so I could get a better sidewall...but who knows I might not be able to drive the turd. If I can get anything under a 1.9 60 ft I know it will go 11s for sure..It went 12.6s the night I bought it with a few hrs of playing around..Only thing it has was the LS6 create..Iv done cam, suspension, gears ect.. since then..
I know its going to cost a bit to get me where I want but my real questions are the heads Iv talked about good enough for my goals..Iv found an LS2 that Im thinking about buying..but I was just wondering how hard it would be to do in the ls1/ls6 blocks..
My car made the power it makes and everyone thinks that I dont know what a tune does for a car. Hell ya Im ganna have one of the better people I know tune it, Hell ya Ill spend the money were it needs to be spent, I just dont see paying for AFR or Trick Flow heads if I can make mine or get a set a bit cheaper and make them work almost as good or AS good. Whatever I decide..the motor I choose to build is going to Boyds Racing in Oklahoma. Eric has done a few motors in his day for a lot of aplications and done a nice stroker motor for my older t/a.
This is pretty much what Iv wanted
An Eagle 383 kit
Have my 243s Ported
Reuse my MS4 or have one Specd out..I dont mind it now..with a good tuner the MS4 is very drivable..but makes little to no power until 3800-4000 RPMS..Great for a street cam..there is a lot better out there for sure but its good for me..lots of rolls...thats what I do.

im building a 393ci with a ls1 block and shooting for 500rwhp.
4.100 eagle forged crank
6.125 eagle hbeam rods
3.905 flat top pistons
254/260 630/625 113+2 cam
extensively ported and milled 243 heads
~11.8:1 comp
ported fast 90/90
we will see if i can hit my goals, but those ive been working with on the build say it should
