Performance Automatic has developed the Pro Fit Bellhousing for Ford engines. This unique housing is cast from a high strength aluminum alloy and is SFI 30.1 certified. What makes this bellhousing so unique is that it is part of their Pro Fit System. This bell is CNC machined to accept the 157 or 164 tooth flywheels and starters thus eliminating any guesswork. A case fill or pan fill C4 transmission can be used with this bell and all hardware is included. Want to change to a Powerglide? Using the same bellhousing, just add the Performance Automatic Pro Fit Ring kit and the Powerglide is a direct bolt on. Maybe a Turbo 400? Just buy the ring kit for the 400 and bolt it on!
