Buddy, a nice v twin engine like a vanguard or something similar would be perfect for that thing! The deep growl of those engines combined with the torque would really make that thing a hot rod!
What that thing needs is an old inline twin cylinder Wisconsin engine with hot rod style open headers. Definitely a cool find man! Keep us posted on the build!
First off THANKS for watching the video i am uploading a video tonight of the engine running i only paid 40 dollars for the frame amd 20 for the engine i havent added up the entire cost of it yet but ill make video of that once im done building this beast. I havent uploaded alot due to the camera i was using sucked as far as quality so i got a better one so more videos coming im gonna show the rat rod from start to finish
