How much is a new LS1 motor?

I think before 2005 closes out, if I have the proper funds, I am going to either buy a new LS1, LS6 or LS2 or just rebuild my current engine. But I've heard that it costs $4000 to rebuild, I would think that you can buy a whole new motor for that much money? At least maybe by next year I could...

Anyway, yea, anyone have a price list for this kind of thing or know off the top of your heads?

EDIT - Make that 5300 For the LS6

Dang I didn't know LS6's compression ratios were so high. I thought they were like the LS1s, around 9.6 or something.

I think the ls1 are 10.4:1 or 10.1:1

I've seen brand new LS1s in catalogs going for around $7,500.

That seems way to high for just an LS1 motor.

Look at paceparts.com they have an LS1 with intake, injectors, throttle body, I think it even comes with a PCM. $6259.

I've seen the LS1 rated as 10.1:1, and I've seen it as 10.2:1:think:. AFAIK, the LS6 was rated at 10.5:1:confused:.

LS1 stock compression is 10.1:1
LS6 stock compression is 10.5:1

The LS1 has a 66.67cc combustion chamber
The LS6 has a 64.45cc combustion chamber

Other than heads cam shaft and intake the engines are the same and use a flat top eutectic piston and the difference in compression is due to the difference in the combustion chambers size.

If you already have an LS1/LS6 engine I would say that the best route would be to rebuild using better internals

For about $6800.00(using your block) we could build a Forged 347 LS1 long block with Stage 2 heads and a custom cam.

I'm currently having a forged shortblock built.

With LS6 intake, Patriot S2 heads, TSP camshaft, Fidenza flywheel, Spec clutch, dampener, ARP throughout, Comp lifters, forged pistons, sized rods, blueprinted/balanced and assembled ... I'm gonna come in at about $4500 ...

It should be a 450-475 crank horespower motor. With all the balancing and dampening, it ought to run very smooth ...

I agree building one up with forged goodies is a nice way to go. Howerver, should you want an new LS6, go to www.gmpartsdirect.com . The have the LS6 long block for $5,030.13. That's 405hp motor in a crate from chevrolet with the Camaro oil pan. BTW, when you get to the site, click on "upgrades" and then click on the Camaro SS and you will see the LS6 longblock button. Good luck.

PS a new LS1 cost $5,901.21 at the same site. I would buy the LS6:) :) :)

if your really looking to buy a new motor you should try to look on ebay.ive seen new crate ls1's i think starting at 1500. you can get used one with like 4000 miles on them for like 2500.

Dang, dont buy a stock motor. U can probabily get an already built stroked LS1 or stroke your current Ls1 for 4-7K. Or at least re-build it with forged internals and a nice heads and cam and come out alot better.

You could probably find a used shortblock for $1000 or even less.

Figure $6000 delivered to your house.

Thanks for the info guys. Will a rebuilt motor with forged internals, blueprinting and balancing be more/same reliable as a new one? Will it keep the same fuel economy?

I really want to keep the fuel economy since this is my daily driver.

I don't know where I got that 9.6:1 compression ration from... :o

Nick, AP Engineering (http://www.automotiveperformance.net/engine.htm) has a great price on a forged 347 short block. They are a sponsor and I hear nothing but great things about them on LS1Tech.com

Check them out.

Scoggins Dickey will sell you a new LS1 motor for $6000 incl warranty. see at http://www.sdpc2000.com/cart.asp?action=prod_detail&catid=120&pid=466

If the only thing you do is switch out your internals for forged, your fuel economy won't change. That's only when you put that 231/237 cam in :bow:

Thats the motor i would get if ididnt get a stroker, that seems like a very good deal. And u could spray a huge azz shot of nitrous into that motor all day long and not have to worry about anything breaking.. And even put any head and cam combo you wanted and not have to worry about the bottom end at all.:cool:
