I've got a 51 Chev 2 dr. sedan with a stuck 216 w/3 sp. I know replacing it with a 235 or 261 is pretty simple. I like the idea of more cubes and am wondering if a 292 would be relatively easy. I'd opt for an auto trans although I still have affection for a manual on the floor. As far as the rear, I know a Nova one would fit (or a brand new one from strange engineering for Nova application). I have heard that the rear spring mounts are offset on the oem torque tube rear and that chassis engineering makes a new spring kit for this. I wonder how much HP I could expect from the 292, say with a cam, headders & multi carb upgrade. Any experiences/thoughts would be appreciated.
