I have a 52 Chrysler 265 that has 115 compression and no smoke. Ran super when I took it out of the car. I had another 265 rebuilt with some modifications and I just swapped them. I believe I have the starter-manifolds-dizzy-carb. I used the engine to mock up some parts and it needs a set of gaskets to button it back up---for more info call---612-207-5853...Thanks
