So im going to rebuild an ls1 block from the ground up, new heads, cam, LTs, everything, and drop it into my 01 MMM camaro. My question is this... Im going to buy a used LS1/LS6 block and get it machined. How much have you guys paid to get the cylinder's machined and get the face's leveled down? basically i want the whole block machined down. thanks

 

The shop by me charges $20 bucks a cylinder to get it machined.

 

Waco crank and sprocket 450 ish dont have the number though i called information.....

 

there is a machine shop near that does engines especially for performance... im not wanting to bore them out so much to were i have to get some crazy *** expensive heads, just want to bore them out so they will run the ls6 head well... anyone know how much they should be bored out to run the ls6 head, max?

 

usually around $500 for the standard block work (bore, hone, deck, and line bore/hone)

 

max overbore for a 99+ LS1/LS6 block is 0.010"....that's all you get.....if you want more bore than that you MUST either resleeve, an LS2, or use an iron block....

 

Keep in mind some shops won't include the cost to use torque plates unless you specify. Also, it's usually necessary to align hone the mains, but even still, that's not always necessary if the block is in excellent condition. My friend's Mark IV 454 block didn't need to be align honed, and it will be a 700hp setup. The shop that did the work on it has done many radical setups in the past with a good reputation. When you shop around, figure in the cost for these extras that some shops consider.

My advice: Go to the most reputable shop you can find. If you have to pay maybe $100 more for a shop with good CNC equipment and guys who really know their stuff, it's well worth it over a rinky-dink place that hasn't touched LS1's before and may not be familiar with aluminum blocks.
