WTB: motorcycle engine or 4cyclinder car motor with tranny?

i know i am, this more or less is testing myself… i could make the laser putter or auto garbage can…(last years designs) but if its something i could build in a night whats the point? ive been working on this for three days, i have chassis almost done, im working on my suspension right now trying to decide how i want to make it… i guess you need to see where im coming from, its been something planed for 3 years now and im goign to do it, hell, it will probally be fun when im done
