Fully agree, this is what I would do if I was you. The money you put in heads and cam and valvetrain will be around 1800 to 2000 bucks. I would rather build the bottom end up first. Callie rods are $569.00 and forged pistions are 6xx something. I would rather do the bottom end and know were you are on that end before touching the heads and cam. If you forge it you can run nitrous and then you still have driveability and no cobra problems.

I kind of like the forged pistons idea since it makes sense, ill be able to throw nitrous in there and with pistons with a good valve relief.. i can mill either the 5.3 heads to 59cc or mill the ls6 heads and get the best of both worlds, high end power and low end torque.. can u mill the stage 2.5 ls6 heads to 59cc or is that too much?[/QUOTE]

I forged my 347 with Diamond Pistions $622 dollars and Compstar Callie Rods for $549. Bought TSP PRC 5.3 Heads for $1093. A Comp Cams Custom Cam 580/580 115lsa something like that. My Diamond Pistons are 9.5 to 1 and N/A breaking the motor in before I put the blower on 439 hp. All this through a Stock LS6 Intake. Now I could run as big of a nitrous shot as I wanted with ZERO ISSUES. And I had a fully rebuilt LS Motor. Then in the future if you want to go Forced Induction you are already set and ready to go. I am telling you this is by far the SMARTEST move. Thats my 2 cents do what you want.

I like idea of pistons and connecting rods too; however i am on a budget, so I might have to save it for the day I decide to go with forced induction. Even tho knowing i could throw a NOS kit on it anytime would be great, I dont think I'll have the extra cash.

Maybe I should start a knew thread but any other suggestions as to what parts to replace on a 135k engine, top end only

Anything else? I plan on going with the ls6 tsp ported oil pump, and double roller adjustable timing set, what lifters? rod bearings?

I like the idea of making big Usable power with the smallest cam. This is because I really like driveability and I dont want to get unwanted attention.

With that being said, go with a Mamo AFR 205 heads, his 224/228 cam, and a Mamo Fast 90/90 and you will have a for sure 450 car with incredible driveability.

Once I get money I will throw this combo on my SS

For a budget I would go with a ls7 lifter and a ls2 timing chain would be plenty. As far as bearings, have tsp give you some options when you call them.
One thing to think about with the bottom end... I would not recomend a heavy forged piston on a stock rod. Save up and do rods and pistons when the time comes. How much are you looking to spend?

I am hoping to see 450 + rwhp out of my combo (mods) in sig, my car hits the dyno tomorrow, as you can see I am going with the stage 3 Livernois heads and stage 2 cam 232/232 .595/.595 on a 114 LSA and a ported 92mm Fast intake and 95 mm PTM t/b from Texas Speed. Driveability was one of my big things in putting my combo together as well....

What is your budget?

I agree. You dont need a massive cam for that goal. Easier on valvetrain, and some killer down low power.

LIVERNOIS STAGE II LS HEADS
Seasoned GM LS2 castings
5 axis CNC machined
Fully assembled
220cc Intake Runner
Intake Flow Rate 305 CFM
Exhaust Flow Rate 235 CFM
New 2.000 intake valves / 1.550 exhaust valves
GM valve seals
Super 7 locks
Livernois dual coil valve springs good to ~ .690 lift
Livernois titanium retainers

those heads plus a 232/236 cam(custom grind i was lookin at for mine) IMO would be driveable enough. then go ahead and throw the bolt ons at it. fast 90/90, fuel rails/inj, LT's, 3" true duals, clutch, and some one who can tune like crazy. note: that oil pump upgrade might also be worth the $$$ while u r in there. (i believe ported ls6 unit was mentioned)

but really its all personal pref. that will decide what u buy.

cam get some good gears and do your heads and cam and you should keep up with the cobra. **** i had 3.42's and a full exhaust plus a whisper lid and stock supercharged cobras didnt impress me. now i got 3.73's and more mods to come. if need be throw an 100 shot for ***** and giggles and you can wave bye bye.

i like how people in here are talking about setups they know nothing about..

"someone said/posted that this setup is good, go with it."

BUT!!!!!!!!

since you want 450 and your an m6...

PRC ls6 heads
ls6 intake (or used FAST 9090 even better)
pretty much any 230+/232+ .600+
410s
free flowing exhaust

that will get you VERY close..

enough that you wont have to worry about many stock blower cobras..


I agree. Maybe an LG Cam also.

I'd like to keep it around $4000 parts. Its 2000 for the texas speed h/c cam package which comes with ported oil pump, timin chain, and pushrods.. then hopefully can find a deal for a ported 90/90 on here.. and LT on here... i figure 1500 for both LTs and intake/tb.. if im patient.. and i still have lifters, perhaps block work, and bolts and bearings.. and i figure all thats in the ball park of $4k

BUT if i wanna wait a couple extra months or so.. ill be able to go with pistons and connecting rods.. I just dont know how many months i can take with my buds cobra embarrasin my Z.. then again if i wait some extra months .. throw a nos kit in there and then its not even a race.. im still debating on which way to go.. bc i know ill end up getting pistons and rods eventually, just dont know if i should wait til forced induction is a more realistic goal

you can do a PRCls6 heads/cam 90/90 setup with full exhaust for around 3k.. thats with all the little parts too..

you can get a used 9090 for around 800 bucks..
you can get stg 1 heads new for 1100 or used for around 800..
cam is in the range of 200-280 shipped..
push rods 90 bucks..
oil pump and timing chain, believe this is in the bal park of 150$ together, been a while though..
depends on headers, anywhere from 250-900..

that on average is aound 2500 bucks... thats leaves you with 500$ to play with to keep it around 3k..

i had 3k in my white car... times in sig..

KillaCamZ28

Are these prices coming from deals on LS1tech or from actual shops.. cause idk how u could get a cam for 280 shipped unless u mean w/o a spring kit
.. and i was pretty set on the stg 2.5 ls6 heads/t2 cam/double roller timing chain/ported oil pump/pushrod package from texas speed for 2000 cause that seems like a great deal IMO and you get reliability after that im looking to find deals tho

lemons12

iTrader: (71)

deals on here... your trying to save money.. i was just showing you what could be achieved with XXXX dollars..

you dont need a double roller.. see if they will knock some off for that...

intakes you can get for under 900 shipped.. headers, all depends on what you want..

KillaCamZ28

Well if I dont get the timing chain i can save $115.. and if i get neither the ported pump or timing chain.. i save 250.. but still need oil pump and a timing chain..
Also should i upgrade the injectors/if so what size?

lemons12

iTrader: (71)

you do need the timing chain.. but not a double roller.. ls2 will suffice just fine..

if you are spraying, upgrade injectors and pump.. if you arent.. dont worry about it.

ms4z28

The stock pump on motor is fine for a h/c/i set up you can just get the prc 2.5 head they work great even more so for a budget build with a big cam and even a ls6 intake you should be able to go 450+ and go like a 37 lb injector unless you spray go a 255 pump and 42lb injectors for a dry shot and you'll be fine also to help the bottom end live go with arp rod bolts and you won't have to worry about spinning a bearing the only thing you will worry about then are pistons if you break one then you can just put forged pistons if you don't have cash for forged rods... The only thing is, is that it's a lit of work just to do pistons only but you will be fine going pistons only on spray or even low boost. But arp rod bolts for sure especially with that many miles cuz those are weak point on any ls1 even more with over 100,000 miles

ms4z28

And lemons12 is right you don't need a double roller at all ls2 will work great that's what I have had on both of my cars

ms4z28

And really for Just the cam swap injectors cam oil pump spring etc., it's in the area of 1200 all new parts... With out exhaust then go Texas 1 7/8" headers and x pipe for about 900-1000 and if you have a4 then a converter and most likely a build trans about 2000 all together and m6 a ls7 clutch or a spec 3 clutch would be good for like 600. That without heads and intake if you get a ls6 you can get it like 400 and heads like 1000-1200 oh and underdruve pulley that like 200 while you have the balancer doing the cam swap if you want to. It gets expensive quick
