Guy brings me a very well built manifold, brackets and diecast aircleaner backing plate.. for a 4 cylinder car..
Damned if they are not CB450 CV carbs,

And the rest is so well built, I mean looks factory..

Later on , a mek-an-ick buddy stops by and I show him, ..and he figures they are off an 81 or 82 Accord.... go figure..
So now I am thinking.. maybe they could be bigger bore hi-po carbs for a 450..??
Anyone seen these..?
