sleeving lq4?????????????
Talk to ERL...I would think its possible but havent personally seen one. The lq series cylinders can be taken out pretty big already giving alot of cubic inches. I would also like to know why you are doing this
this is a quote from yellow bullet. LA Sleeve part# FL-3188 would be ideal for you. So would a Melling 590298.
Some OEM and almost all aftermarket aluminum blocks are fitted with replaceable sleeves. All the rest are made with the "cast in" liners meaning iron cylinder liners where placed in the mold and the aluminum poured afterwards, making it impossible to just remove the liners. LS blocks are as or no more difficult as any other that share the same design. Early on, a few machinist where just boring the holes out and driving straight, non-flanged sleeves in just as if it where an old skool SBC. It didn't/doesn't work well as the sleeves had a tendency to drop (slide down). Any machine shop equipped to handle flanged sleeve installs will have no problems provided they keep in mind the proper interference fit and/or the expansion rate of aluminum. For me, flanged sleeves are too time consuming to justify installing them (at this time). If I had CNC stuff, it would be painless.

second quote from y.b. from billyman on yellow bullet
and other problems !like the 6.0 factory block isn't siamesed.]
This is where the custom sleeves come in.........or at least custom modified sleeves. Flanged sleeves aren't necessary on iron blocks as they are for aluminum so no specialty there. But, when we get into the big bore 4.125"+ stuff, the sleeves have to be cut (flat-sided) where two sleeves meet side by side................just as the sleeves ERL installs and as are the factory sleeves in LS7 blocks for example. This is nothing new as it is standard practice in sleeving old skool SBC 400 blocks.

sleeving The reason I ask if anyone has sleeved lq4 block is because I want to make 427 out of it without having to put the 4.1 stroke crank. The machine work getting done is no problem I have very good friend to take care of that

Your looking for Darton MID LSx Sleeves. They come with a rough bore of 4.100. Installation is critical. Never heard of anyone using them in a iron block but often wondered who had one.
it will work just fine in a iron block.... but after all of the time the price of the sleeves and the machine work u can buy a lsx block for about the same price. mighty mouse has a good deal on one.
Excellent article.

Considering the cost of sleeving versus iron LSX blocks priced at $2000, it's beginning to be clear why LQ4 blocks aren't sleeved.

Sleeving the iron blocks I have installed Darton MID sleeves in the 6.0 iron blocks before the LSx iron blocks were available. It is cheaper to purchase an LSx block than it is to MID sleeve the LQ4 or LQ9 blocks.
I also install MID sleeves in the iron 6.1 Hemi blocks and they are not inexpensive to do either. Looking forward to getting my hands on one of the new 6.1 aluminum Hemi blocks!

sleeving Well guys I have access to many things here and I was thinking of sleeving at reasonable price but its not possible. I will just build a stock bottom-end 6.0 with 241 heads and ls1 intake for now. Any of you guys have a suggestion for cam with what heads and intake that I have already?
