This is a McLeod 8630 bellhousing with my trans pattern overlaid on it. This is a swap bell, GM V-6/V-8 block to a variety of transmissions including the T-5. As you can see, the bottom two holes are close enough for (my) measurement error but the top two will need to be relocated. That's why I'm thinking the 4 cyl box has a ba$tard pattern. Anyone see a problem with re-drilling this?
