If you don't mind me asking, what kind of $ do you have in your W8 build?

It's a W9 R3 deal and I bought it from an engine builder that built it for a racer in Venezuela and that gentleman moved to Spain so I bought his dyno time only complete carb to pan w/ vacuum pump for 16k.....made over 900 at the time.
