If you wanted to, how would you add valves and rocker arms to this?

i made this 3 years ago but if you wach my video--- http://www.youtube.com/watch?v=U0Q9RbXeMHc
you can stop the video when you see the valves, i used elastic bands for it but it wound work better with small springs. its all a got to help you so i hope it works out for you.

TO MAKE IT RUN USE A CORDLESS DRILL TO ONE END OF THE CRANK SHAFT ITS REALLY COOL

needles300 (author) in reply to lilbigmanbJun 9, 2010. 3:32 PM

instead of using black hinges can we use one gray connector and allternate through the crank shaft so its a v4 ND NOT A V8

needles300 (author) in reply to superbestknexNov 26, 2010. 11:39 PM

you could cut it to make one. it won't be a V engine, you would make it a inline engine.
