Overview
A big block Ford truck or motorhome from the late eighties to the middle nineties is the target for this BBK throttle body. Two blades sit in an aluminum housing with the stock flange pattern.
Consider it for a bolt-in airflow upgrade on the engines named in the listing. The limits are the narrow application range and the absence of any detail on included gaskets or sensor fit.
Who it's for
Owners of the listed Ford trucks who are already working on intake and airflow and want a larger bore at the throttle. Those with other Ford engines or later trucks have no listed support.
Pros and cons
- Twin-blade high-flow design
- Uses the stock flange
- Sold individually for single-engine builds
- Narrow application range
- Gasket and sensor details not given
- No flow figures listed
Performance notes
A larger bore and twin blades reduce restriction at wide open throttle, which matters most when the rest of the intake is also freer. The listing offers no flow data, so the gain depends on the engine's other parts.
