This may be a longshot, but I figure i'll see if there's any interest.



I have a LT1 block that has been bored out .03 and has machined reliefs to work with a 3.75" stroke crank . The crank is Eagle's cast steel LT1 crank (10352375057E) and has been ground .01 under about 2000miles ago. The rods are Eagle I-beam SIR5700BBLW. I had a machine shop re-hone and install the .03 pistons when I built it, but I think he was too aggressive with the hone and didn't check vs the pistons, as it has piston slap currently. The blocks are good to .04 over though, so it should be okay with a overbore and new pistons, rings and bearings. I'm located in Oakland, CA and would prefer local pickup, but could arrange shipping if someone is really desperate.

just sayin they didnt push down and pull up hard enough to get cross hatching right.
but you can recross hatch it .
if those are forged pistons they have to warm up and swell to operating temp before the slap goes away
if every thing was sized right .

Don't ever use that shop again. He didn't even bother to remove the ridge at top of cylinder. The slap you hear is probably the sound of the top piston ring hitting the ridge at top of cylinder. Don't worry about the noise. It will go away when top ring breaks on all the pistons.
