just curious.....

 

My block has a sleeve in one of the cylinders, courtesy of Don Lee Auto.

Not a big deal, but it kinda sucks when you learn about it after your fresh engine built by them fails.

 

For larger CID reasons or just to save the block?
IIRC there was someone by the name of Hoover(something) on CZ28.com a few years ago that sleeved a block to do a 420 or 427cid LTx. What I remember is it working alright for the application, however it was tedious costly. I vaguely remember the car running well and was driven often

 

Sounds like SS MPSTR's scenario was a "save the block" one.

 

My #1 is sleeved after I had a piston disintegrate and the wrist pin tear into the cylinder wall. It came out fine and haven't had an issue, but the sleeve might not go far enough down for a very large stroke application, it only goes about 3/4 of the way down the cylinder.

Although I have a feeling you're talking about sleeving to increase cu in, not repair.

 

My post/question was to the OP.

 

You wanna go bigger?

 

you're right, more cubes... an SHP block would be an obvious choice in that situation now, but just wondering if someone had done it before. Obviously if people have done it, it was probably 10 years ago before the LS1 era and the only other choices were an iron eagle, little m, rocket, etc block ($$$)

 

Not sure if you frequent CZ28.com, but I think the mod of the LTx section, "injuneer" might have far more detail on Hoover(something)'s setup...

 

yea i started over at cz28 years back.. there used to be quite a few bright folks there, seems like most have moved on.

 

I have a 2 bolt 388 and a 4 bolt 396 with a sleeve on each one.

 

"Injuneer" Fred is on this board...page him

 

I had a sleeve added to a motor that did pedestrian duty for years with no issues. My machinist said they dont go all the way down because of structural rigidity, and the process is very delicate, have to heat the block before pressing the sleeve in. I went .030 over and he bored that cylender (with a large gash from a wrist pin) i'm not sure how much, and then had to lip it if I remember right and then press it in.

 

as with this board

 

From what I've seen they all moved here and LTxtech.com.

I've seen Fred talk about some guy from somewhere sleeve an LT1 for a 427ci everytime a "how big can you go with an LT1" thread pops up but who know's if its really true.

Hell, I've never even seen pics of those RARE "big cube" LT1 blocks that came from GM so long ago.

 

One sold on ebay right when dart was "going" to make a bigger bore block. I think they got 3K for it and if I would have known that dart was going to back out I would have bought it for a NA build.

 

Dart backing out of the "big bore LT1" pissed A LOT of people off that day. Especially after leading us on practically for a whole year. Had they produced that block I would have been all over it like white on rice.

 

I definately would have liked puting a 428 graphic on the side of my Pontiac.
