If only "28" were made, those are more rare than lips on a chicken. Good luck finding one and I hope you have some very deep pockets. LOL

I have one, do not want to sell. I contacted someone at Hilborn, and they guessed that they made about 75. Who knows. The ports on a SB chev are not too far off, but the angle and all the rest of it would take a lot of work. I once thought about trying to adapt the 2 piece B/RB ones, AKA make or buy intake port side plates, make a "base" with the side plates and valley cover made, and of course fab some sort of water manifold, then, rework the 2 piece units (cut them into 4 piece!!) and rework/ adapt.

I also had bought (cheap, then) a pair of alike bike 4 cyl throttle bodies, but they actually might be too small.
