Old school LS2 crate engine

[thedude327]

Found this while browsing over at pace performance's website and it looked interesting. Is anyone here at Lateral-g using something like this? Any thoughts on doing a swap like this??

Thanks for any input

DUDE....

You can do this to any LS motor you find... EDELBROCK makes a couple different "CARB" manifolds for the LSx motors and they have a controller for the coils...

Chevrolet also offers carb manifolds and a could of 'carbed' LSx motors. Way kool old skool. They were supposed to offer a carbed LSx 454 -- 620hp version but it hasn't hit the streets yet last I checked.

That's a pretty cool, complete setup.

I know. I'm waiting to see some reviews on that bad boy carbed LSx 454. It was "supposed" to be out last October, I believe.:_paranoid

i am running a 5.3 ls carbd on my 69. runs great.

I like but the price seems a littel high for a carb or am I wrong?

There is a LQ9 with a carb and dizzy going in a second gen here. 1970CamaroRS is the owner.

The price on it does seem high for a carb motor but it is a new LS2, dist set up, carb, intake and all acc. I am sure if it was all priced separatley it would be a bit more. And if you add in all the extras needed to use the EFI it is still cheaper to use the carb version. (when comparing new to new)

That is the same thing I was thinking. Adding up the dist. cover intake and front drive plus the engine didn't seem too bad. I would prefer this crate engine setup using the LS3 with GMPP's Hot cam.I'd bet that a Hot cammed LS3 would produce close to 500hp/tq numbers. I wonder if pace would consider doing that as a crate package? I'll have to call em' and find out. This package does seem like it would get you on the road pretty quick though.

Took me less that 3 seconds to google -- LS3 CRATE ENGINE and come up with a GM offering - you can even buy it from Summit Racing or any other GM Dealer... Here's the description:

These GM Performance Parts LS 376/515 HP LS3 crate engines use an aggressive camshaft profile and a GM Performance Parts carbureted intake manifold to put out 515 hp and 575 ft.-lbs. of torque. They start out with a cast aluminum 6-bolt engine block with cross-bolted main caps and add a nodular iron crankshaft, powder metal connecting rods, and 10.7:1 compression ratio hypereutectic pistons. They also include a pair of aluminum LS3 rectangular ports, 68cc cylinder heads with 1.7 ratio rocker arms, a GM Performance Parts hydraulic roller "hot cam" and lifters, and a carbureted intake manifold. Those parts allow the GM Performance Parts LS 376/515 HP LS3 crate engines to provide you with a powerful small block that can be driven on pump gasoline.

Greg,
I've seen this engine in the GMPP catalog, what it does not include is the distributor drive kit and the acessory drive hardware. Also, I believe that it used the ASA cam which specs out differently than the Hot cam. This moves the peak torque up to 5000 rpm vs. 4500 with the Hotcam. The lower peak torque rpm of the Hot cam is more street/autocross friendly IMO. Actually, I wouldn't be surprised to see GMPP start to offer LS shortblocks soon, so that you can pick a set of heads and cam without tearing apart the engine first to optimize it for your application.

I would love to see them offer a short block LS2 or LS3. Even a iron version. It would give the builder a better choice of parts to use without having to toss out or resell heads, intake and more.

[GregWeld]

I wasn't trying to pick a single engine out for you - rather - just showing that there is LOTS of options out there - both factory and non factory built CARB LS engines.

I'll spend far in excess of that the GM LS carb motors cost -- just to REBUILD my Dart Little M motor...

So they're a BARGAIN at 9 grand and under for complete motors... I'm the STUPID one for wasting more money on an OLD SKOOL motor.

:faint: :faint:

....as the LS6 collects more dust.......:D

It's a stupid little baby motor... might as well run some lame ass 350...

Wouldn't call you stupid for using a dart little m block. If I had one already, I'd use it to. It's just that when comparing costs starting from scratch, the difference between an GEN I performance build up and an LS crate with all the extras is about a wash. Just don't start comparing 15degree heads to 23 degree heads or iron blocks vs. aluminum blocks because there's where things start to point in only one direction............again, only my thinking.

Nice looking car/engine bay. Any more pics on another thread?:thumbsup:
(I don't want to hijack THEDUDE's thread here.)

I just can't see a Chevy with the distributor in the front. That ruins it for me.

I have that engine, but it is yet to be intalled. You don't have to run a distributor to have a carb on an LS

How about 590ish HP, would that still ruin it for ya? :unibrow:

I have no problem with a carb intake setup and the front mounted distributor in the original link that I don't like. Might as well run a SBF.:D

That is one nice looking LS motor. Easy to set the timing to I'd bet !!:thumbsup: Any specs on the internals, cam, heads ,etc. ??
