I am getting things in motion to rebuild an L61 but with a used LSJ block. I was wondering what all components you have available that I would need. Trying to see what you have all at once so I can purchase the parts in a single order. First I will start with what I think I will be reusing.
-L61 head
-ARP head studs (from L61 block hopefully work with LSJ block)
-Forged rods and pistons
-crank (Are OEM L61 cranks available?)
-Timing chain kit from L61(pretty much new kit that I bought from you with upgraded bolts)
I did not replace balance shaft and water pump components. Plan on going with either balance shaft delete or neutral balance shafts.
-Oil pan
-All intake, exhaust and pulley components.

Now what I think I need
-Sleeves
-Main bearings
-Con-rod bearings
-Seals? (not sure which ones I need)
-Gaskets (have spar exhaust and intake so just head gasket)
-ATI super damper
-NBS or balance shaft delete kit

I may be missing some things but this is off the top of my head.

 

That I could find CED has at least:
-Cylinder Sleeves
-Main bearing
-main seal
-harmonic balancer bolt
-head gasket

 

You dont need sleeves, could have it honed out a couple thousanths and get custom pistons.

 

Custom pistons vs. sleeves. It seems the cost is comparable depending on how much I get charged for someone to put them in. With stock bore I can reuse the pistons I already have. Doesn't really matter now I already ordered sleeves.

How much about are custom pistons like that for future reference?

 

I guess i wasnt thinking along the lines that you already had pistons. I paid 650 for diamond pistons and rings

 

Yeah if I didn't have pistons already that would be the way to go. If I can get sleeves installed for around $150 or less it will be a wash in my situation.

 

Have you thought about going with stronger sleeves? I think for around $800 you can get Mr B's sleeves installed. If you wanna install them yourself you just need the sleeve puller

 

I've thought about it but really with my L61 setup I think my crank is the weakest link. Doesn't the LSJ block have a bit more material around the sleeve than the L61? My L61 block held together. Really this time around I won't be adding much power just the equivalent pulley drop by using the OD ATI and whatever Foximus's head does for me. FYI I am running 2.9" pulley on TVS currently.

 

The crank is not a limiting factor at all the design of the block makes it almost impossible for the crank the flex on these engines. There is a guy on facebook making 700+ on a cast crank. These cranks dont break.

 

Well that is good to know. Isn't the LSJ block good to 500 hp or so though?

 

You should be fine with a tvs i dont think youll break a stock block
