Small Block Bellhousing That Fits 4.8" 4 Speed Bearing Retainer

I was looking at an 18 spline with the 4.8 retainer. This is why I asked. Have decided after my research to stick with the 23 spline. Should serve me well if I do not do track time or slicks.

Thanks to all that responded.

4.8 can be a 307 or 308 bearing. If it is a 307 bearing you can swap bearing retainers, and be good to go.
