Default Question about the LS 2 block

Did the LS2 block come standard in any Chevrolet? I am looking for a used LS2 block to resleeve; as I am looking to build a rather large small block. Thanks, James

I believe that it just came in the 05 Vette & GTO and 06 SSR. I'm sure that others will chime in, however.

Why?

Why start with the LS2? You can stroke the LS2 to 412 cubic inches.

The Warhawk block can run to 454ci stock, and to 502ci bored and stroked.

Why the LS2? It is not your cheapest - or best - option for resleeving.

I was told by Steve over the phone, it was the best for resleeving. It's cheaper than the warhawk. I'm not looking to build anything exotic, just in the 1000 RWHP range. James

Something just doesn't quite seem right about that statement

That is actually the upper limits of what I might build. The motor will be around 600 RWHP N/A, a minimum of a 250 shot, single stage and a possibility of a two stage 400 hp fogger kit. Therefore I want to build the bottom end/block to withstand 1000 RWHP. I won't need the little blue bottle except when at the track.

The Warhawk block is a possibility, but it would be nearly twice the cost of a resleeved LS2 block which is plenty strong enough for what I'm looking to build. I can use the money in other places like the rotating assembly to get better quality pieces. James

How are you going to keep the heads down on an LS2 at that power level?

Good luck - and please post your results

You weld the heads to the block!

Seriously, I didn't have a problem with the SBF keeping the heads down. Head studs, good head gaskets and a little extra torque should withstand the cylinder pressure. If I run into problems, I may have to go with the Warhawk block and utilize the extra head studs; time will tell. I don't get out of school until December and won't be settled into my new home in San Antonio until the end of January. I am not looking to start this project until late summer of next year. I am looking for parts though. The best part of this whole project is the tranny is a stick. James
