Small Block Bellhousing That Fits 4.8" 4 Speed Bearing Retainer

They did not make a factory small block bellhousing with the 4.8 pilot hole. Aftermarket, Ansen, Lakewood, yes.

I have had at least two factor ones in the last year. I should have recorded the casting numbers. I guess it's possible they could have been enlarged.......but two so close together?
