More of a question about dual springs. Seems the retainers could easily be larger than stock specification. And yes, I think the 273 had smaller retainers than 340-360
The SPRINGS are larger than stock, so the retainers are too, since they span the entire diameter of the spring. Those look like at least 1.5" OD springs. Pretty fat. I think he's got a lot of good parts there. Probably a pretty nice engine.
