Big Port version #6 cylinder head.

The cure:
We have machined and inserted larger intake spigots.

Bare head.
The do-it-yourself version.

Apologize for the camera work ..... ports are very difficult to photograph.

Well traveled Fast by Ferracci cylinder head.
Well traveled cylinder head?

Yes,
Many years ago we heard of a extremely fast and nearly unbeatable TQ mini sprint car in the New York area.

The TQ midget was going to retire and we purchased the motor to see what Ferracci did to the motor ..... most of the motor was pretty normal except for a few things in the cylinder head.

The most interesting part of the head was the 15 degree upwards exhaust ports. With a few changes to the cylinder head and building a exhaust system we noticed the head made some great power.

Years later .... the FBF cylinder head was sold and about to be used on a TQ in Indiana. Before the head could be used .... the head needed to be adapted to a large Engler fuel injection system.

The head was sent to Vance and Hines back room to adapt and make a few changes. The owner apparently knew the boys at Vance and Hines.

Well traveled!!!    Anyway,  On a chassis dyno this head made approx 126.2 horsepower with a 67mm bore.
 Did we mention these numbers were achieved on the chassis dyno with big tires?

Bare head.
