A 5.7 block can be sleaved with darton sleaves and you can make it a 427 if you like and you shouldn't be limited by the block as far as HP. There are a number of different blocks GM made yeah they made Iron and aluminum 6.0's and now 6.2L's. 6.0 have a 4" bore and the 5.7's had a 3.898 both had 3.622 stroke crank the later ones have 58 tooth reluctors and the earliers a 24. That is a quick run down hope that helps.

LS2s are 4" bore with siamesed cylinders...way different than a LS1 block...

if you're looking for a 408, best to start with an 4" block...

i have heard of allot of horror stories when it comes to re sleeveing the ls1 block.

i would just grab an ls2 block and make a 408 from there

do not use diesel sleeves, if you do decide to re sleeve the motor, use sleeves that where designed for the engine and make sure you get somebody that knows what they are doing to do the work.

Sleeves added to the block are great if u have a good place install them I'm running a sleeved block works. Ls2 is fine for

I would just start with an lq or ls2 and go from there. Machine work from sleeves would be killer I'd imagine

A Darton MID sleeved LS1 block is a very strong and expensive option. You must install wet sleeves in a LS1 block where you have option of wet or dry sleeves in LS2/3/7 blocks. The MID series are a great design but need to be carefully installed.

Plan to drop about $3K for the sleeves to be put in. That does not count line boring or other machine work to finish up block. Probably should also get billet caps installed while you are pouring money in.

If you are really planning on running 20 psi - my suggestion would be an iron block for a whole lot less money. LSX would be another option and still be cheaper than sleeved LS1.

For $2600 ERL will do there superdeck1 This includes billet caps and all the machine worked needed to have a block that is ready ready to assemble. Your estimate of $3000 is high

The $3000 was for a Darton MID sleeve job - does ERL use Darton sleeves for $2600? 4.125 bore?

Try going to ERL website. I really dont understand all the posting of misinformation and question in this thread that are easily answered in the ERL website? See quote from website below.
Chevrolet LS1 with the ERL SUPERDECK Ι system and Darton sleeves.
This particular LS1 has 427 cubic inches of displacement with a bore of 4.125” and a stroke of 4”.

The ERL price looks very good. The pictures of the superdeck are cool but it appears the Darton sleeves they use are different from the MID series. Look at pictures from Darton's web-site for MID and you will see a difference.

Im sure ERL knows what they are doing and are using proper sleeves. I dont get why people dont just call and ask or email about the product if they are so interested instead of taking a shot in the dark guess or saying something that only carries some truth within it.

OP, with that much boost, id go with the 4'' bore block. Save the hassle and do it right.

No, we do not use the MID sleeves. Our sleeves that we machine in house are the same ductile iron but we machine them for our specific application that has been engineered for these applications. Our Superdeck I has been proven time and time again and to my knowledge I don't know of anyone that has pushed a stock sleeved block harder and longer than the Ohio Boys have with our Superdeck I blocks. I would welcome any of you to pm Mike or Steve with the Ohio Boys to hear about it first hand. We are always improving our product and looking at ways to increase the quality, strength and reliability of our blocks. Please let me know if I can answer any questions you all might have in regards to our product and services and I would be happy to help. Thanks!
