Sorry, they were 500efi that had aluminum heads, closed cooling, and the R-tech supercharger installed on them. They have been reprogrammed.

Realistically ask 1000 and take what you can get. You contacted me on Ebay with your 2 , bob at mefiburn has been charging guys like 2250 for one with programming, I haven't had any offers or interests on one I listed BUT I DID get several inquiry's on doing reflashes and custom programming which is where I make my money, Smitty
