Ls1 Vs Ls6 crate engine

I understand,my t/a has gotten a moser 12 bolt and performabuilt stage 2 (2000 stall) this year so funds are tight till income tax time.if no ls6 engines are available then, well I will have to go another route (prob. ls3) my car rarely sees the dragstrip and I want to keep drivability close to stock,so I was thinking of the scoggin-dickey z+221 cam if it would work with my car's stall.If I do decide to go gen 4 with the ls3 what is needed to make it work in my t/a. Thanks, david

If you have a stall, you can fit more cam in. A 2k stall does not give you much room. The Z+221 cam does not require a stall. I would use more cam. Something in the 224 to 228 range. It would take a more serious cam than what you are set up for to make 400 at the wheels.
You can figure it like this. At 20% loss, you would need roughly 480 at the crank. I could see a well designed 224 to 228 cam probably breaking that, but you would be at the limit of that stall to help with drivability. We do have some cams avail that can help you with that though.
The LS6 is 3200.

Yep, LS6 is worth 50hp over the LS1. Half the additional horse is the cam (204/218 .551/.547 117 vs. 197/207 .469/.467 116), other half is the better flowing 243 heads w/ more compression. Modded there wouldn't really be a difference if you're planning on heads and a cam.
That 402hp LS1 had a catback with no engine accessories and was most likely a happy dyno.
EDIT: just saw this is an old thread, anything bigger than a 220 range cam with over .560 lift should meet 400rwhp on a LS6. For an LS3 you would need to spend a lot on adaptors and 58xto24x conversion box. Should be about $800 plus the crate engine at $6200.

Cool,ls6,fast 92 intake and tb,and Z+221 cam sounds like what I want,btw the car already has a slp lid,k&n filter,coated long tube headers,ory,and magnaflow catback.I am planning to install a cutout also.should be more fun than my 207,xxx ls1.

I'm not trying to say something bad about LS6 engine , I know it is great engine as stock but for someone looking for modification on that $3300 .. you can have an LS1 with forged rotating assimbly + LS6 CNC Heads + your choice of cam !

It is not bad .. but it is the correct way to do it ![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)
Seriously .. I cannot imagine to spend $3300 for stock LS6 engine and then also start buying a cam, valvetrain, timing chain, oil pump ..... etc of mods ! .. and at the end I will gain less than X barns Heads/CAM LS1 power ! the difference is that you will spend a total of $4000
But if you got a used LS1 engine then through forged pistons/rods + good heads and you choice of cam .. you will have an engine that will love up to 200 shot of nitrous with the same or less price ! ..

What are longblock ls6s going for? My car just got a moser 12 bolt and performabuilt stage 2 w/ 2000 stall this year so funds are very tight.also with the trans/stall will the stock ls6 cam cause any issues and what cam would you put in to get to 400 rwhp? Car is a driver that rarely sees the dragstrip and I want to keep factory style driveability just with a little more power than a ls1.I was thinking the scoggin-dickey z+220 cam if it wouldn't hurt drivability.thanks,david

Why would you spend all that extra money for an oil pump, timing chain etc? The oil pump is a new ls6 unit, which is very good, an LS2 chain (still very good) plus lighweight valves.
We can cam this engine with springs and pushrods for $4k. Any cam.
The jury can go either way on this, but even though you say you are not trying to knock the engine as is, it sure seems like you are.

I'm not knock the engine, I'm only trying to show better ways
For example, let say someone with 2001 Camaro SS M6 with bolt-ons ls1 making 345 rwhp / 360 rwtq
Is it worth to swap to ls6 engine ? .. for only 25-30 rwhp ? ..
As a performance when you have aa badget to buy that new LS6 engine.. do a H/C LS1 and it will sure perfrom better than that new LS6 ! with half price ! ..
Put in mind that new LS6 engine is gonna come with stock 243's while if I did it in LS1 will buy a CNC ported heads, better valvejob, your choice of springs ! ..
Here is another example and please I want your answer .. If we have trickflow 215 and MS4 cam with all valvetain and we installed them in an LS1 and in LS6 .. what's the power difference in both engines on F-Body ?
LS6 is great engine as stock specially on that light C5 Z06 .. but when it comes to mods .. both LS1/LS6 will perform and dyno the same

This thread was originally crate engine vs crate engine. As in someone is looking to purchase either one. For the price, the ls6 we have as such cannot be beaten.
If you are looking for an engine for the same price as a rotating assy, then its a moot point and if you are looking just for more power it is still a moot point to change out an entire engine like that. UNLESS you have demolished your ls1 engine or dont have one to start out with, or you can sell your ls1 and change to this and come out better on the exchange.
The other reason is if your ls1 is not usable anymore as in being rebuilt (out of spec) or just tired and worn out. The 01/02 f body cars did get the ls6 block in quite a few of them as well as the intakes. Then the only difference is the heads and camshaft.
Each way has its own pros and cons. But they each have their own reason and application.
