Welcome. How cool is it that you found our site! Many guys here to lend a helping hand, we may not be familiar with Russian V8's and Russian cars, but, hot rodding is improvising at it's best, and there are guys here that do that very well! I linked the engine you posted and bodies below. I think they will make one fine hotrod! The last one looks similar to a Holden(australia) or Chevy (here).
