I have a 94 z28 convertible for sale. 25,000 original miles but not original engine. All stock

I bought it with the #1 piston rod sticking out of the pan and into the rack and pinion. When I tore it down I found a jasper engine in it with 23,000, so it’s the third engine. And, being an old Chevy guy, thought I had the wool pulled over my eyes, when I pulled the LT1, rolled it over and found a 2bolt main. So why? Why did Chevy ruin the LT1 with a 2 bolt main. And I put it all back together with 2,500 in new parts, optic spark,Taylor 8mm wires, new rack and pinion, stainless steel rotors, Kyb shocks, water pump, and more. Also probably wasn’t the best engineeering running that cooling line to the top of the heads, just me.

I love driving it, it sounds great, it’s a great investment, and it’s in my garage, it comes with extra trans, and rebuildable LT1 that needs sleeved and more.
