Rob - good source (NHRA drag rules) and I agree they are probably at least "relatively" correct. I am a bit surprised that the difference is only (altho that is a lot of weight in drag racing terms) 75lbs from 300 DX post sedan to malibu sport coupe. I am not "buildin'" anything. Doing some research and chasing an unsubstantiated notion of the COPO possibly being applied to the 300 DXs. The sedan would be the ultimate platform for the COPO (lighter weight, stiffer body). Interesting that you should chime in first as I am interested in the memo from GM you mentioned earlier about COPO only be available for the Malibu line and not the 300. As you know, in life, there are always exceptions to the rule. Any chance you can post or pm me a copy of the memo mentioned above? Thanks!
Interested in any other weight inputs. Anyone actually weigh their personal rides?
