junk or usable? I picked up a lq4 from a 01 3/4ton. I knew there was 2 rods that broke but figured I take a chance.. I was hoping there wouldn't be any damage to the lower part of the cylinder. . I wasn't so lucky. The damage doesn't look to bad. But before I take it to the machine shop..am I wasting my time? does anyone else have experience with simular issue?
Why junk? The damage is below the rings. Why can;t you grind out that damaged area and use it? Cylinders are cut like that for strokers.
I'm not an LS expert, that's why I ask.

A stroker might be machined at the base of the cylinder to provide clearance but that is a different operation than debris smashing around and potentially cracking beyond the missing material, like possibly to water.
I would want more thorough inspection, carefully grind it smooth and magnaflux, or pressure test, something............

new guy with oil psi issues hi guys! as the name states my name is Dan and i have a 2000 camaro SS. anyways i have a bit of a issue.
ok so my car. it has a LS1 that i have done some work to. she has 243 heads with otherwise stock valvetrain. stock lifters pushrods and rockers. she also has a fast 92mm intake with throttle body. volant cai, hooker LT headers with catted y pipe. borla cat back with cutout.
the issue is low oil pressure, changed the pump to a mellings 295. still getting 10psi at idle. took pump back out and shimmed the spring(3 washers) and still getting 17-20 psi hot idle. cold idle she gets 55-65 psi. going down the freeway she gets 45-50 at 70mph. im running mobil 1 10w30 with a quart of lucas...stp filter. car has a 160 degree thermostat....what gives? also tried 2 different oil pressure sending units. 1 from autozone, one from advanced.
