I know I'm just discussing this with myself here but I wasn't measuring correctly. There is a 0.406 mm difference from the front of the #1 piston at TDC and the rear of the #1 piston at TDC. For the standard guys out there, that's 0.016. I'm pretty sure that it's bent. I'll be getting that 3.0 block I've been looking at. I'm wishing now that I had kept that "91 350SDL I bought for $500. It had a factory replacement engine in it and had less than 125k on it. UGH!
