I have a 1984 fiesta xr2 im thinkin of puttin it on bike carbs?

I think that would just be sick and wrong. So, you'd better give it a try. I'd look for four carbs off a bike with similar displacement. I hope you know how to weld, because you'll most likely have to make four manifolds for it. I had a similar sick idea involving a Buick V6, the lower half of a fuel-injection manifold, and six Stromberg one-barrels.
