I really hate to even be asking this, but my adventures in trying to rebuild/tune old carbs have been utter failures.
I own a Holley 570 CFM Street Avenger I bought new in 2003, and has only been used on a few engines during testing and only seen a few street miles. I paid between 250-300 for it on ebay (could probably find the original email receipt if need be).
Since this is now an 8 year old carb (though still in very nice shape), and it was effectively something I have laying around, is it in the spirit of the rules to FMV it, or should I value it at what I paid for it originally? And if its ethical to FMV it, about what would you consider it worth?
I'm in a serious challenge budget crunch at this point, or I wouldn't be asking this. I think the only FMVing I did in the past was on stuff that was given to me. Heck, I'm considering buying a remanned 750cfm Edelbrock for $200 just to add a little leeway in my budget.
