PFA Reproduction Vantage Weber manifold set CNC ported

We have been working hard to reproduce an original type vantage manifold set to compliment any 3.7L / 4L 6 cylinder engine and we have come up with these manifolds.

Due to our experience we recognised a few shortfalls with the factory arrangement and have included some modern thinking and technology to make our manifolds stand out .

Our ports have been revised and come as standard with CNC machined ports with improved size and shape that helps make fitting a “Vantage conversion” a bolt on procedure without having to mess about with over porting the cylinder head , We designed our manifolds to work with a standard SU 1.5” port size cylinder head as this is in a majority cases the most common type cylinder head casting that is upgraded to a Weber arrangement.

These manifolds will fit onto an original larger port Vantage type cylinder head and as a byproduct of good engineering there is no decrease in airflow and we have found an improvement in throttle response and drivability with the more refined port layout.

we have also improved the brake vacuum port area so as to present less turbulence on the roof of the port.

These are sold as sets of three and come with throttle spindle bushes fitted
