I have a 98 LS1 that I was building for my 84 z28, thought the bores would clean up with a hone and boy I was wrong. I need all 8 sleeves, and if I can do it my self it will be cost effective. Speed pro makes a replacement sleeve for $33ea and melling for $55ea. Ive done my fair share of engine work and feel good about it but would like to hear from someone who has done it. Can I heat these and knock them out like the land rovers? I don't want to ruin a block that I can sell if they HAVE To be bored out. I could buy a brand new LS1 block from summit cheaper at that point. Thanks in advance!

They will not press out. They have to bored out on a machine.

Hi ALL, WARNING : The "early" LS-1 block is weak.

The hole between the Main/Cam Tunnel is KNOWN to crack between those points.
The Head Studs have different lengths at the block ends causing bores to be out of round.
There is no provision for the timing chain Dampener.

THUS = Bad Investment

Hey you an aluminum 5.3, l33 preferably, bore it to ls1 specs and drop your guts in. $300 all day for a shortblock here
