403 bell housing pattern
« on: February 22, 2019, 03:40:05 PM »
I have two cars. One is a 79 ta with an olds 403 and a turbo 350. The other is an 80 or 81 non turbo 301 4speed. I was wondering if anyone knows if the 4 speed will bolt to the 403?

They are BOP pattern, the 403 is an Auto-only engine. It does not have the the machining for a pilot bearing to convert to manual.
