Dimensionally, the BBC rod will probably be slightly less massive around the B/E than the factory GMC rod is, even in an H-beam design. I think if they could make the housing bore smaller for tlowes application, they would also profile the B/E to be more like the SBC journal it represents, or you would have a rod that would end up weighing 900g.(LOL), and that would be ridiculously heavy,even for a 292 engine. I think if tlowe has a shortblock laying around, he might just look up inside it with a flashlight, and rotate it around and just see how much extra clearance he has for a beefier rod. I know that with all of Cotton's 292 engines, the cams were ground for clearance on all of them. That might work for a steel roller billet, but would weaken a hydraulic or solid flat tappet camshaft too much....
