tunnel port fuel injection

This is a custom made mechanical fuel injection system for a 427 tunnel port. The throttle bodies are made by Tecalemit-Jackson, an English company, who made fuel injection systems for road racing. These are the 52mm throttle bodies, as compared to the 48mm. Each throttle body bolts on separately, to a weber 48IDA bolt pattern. This particular system has been modified to a hilborn style fuel metering system, a continuous flow, and doesn't have the Tecalemit-Jackson metering system. As there are no venturi's in the throttle bodies, which restrict flow, these 52mm throttle bodies shouyld flow as good as 58mm webers.


The intake is an original 427 tunnel port that has been extensively modified, I'm not sure if it was modified by someone like Holman-Moody ( a Tecalemit-Jackson dealer), or it was done in someone's garage, but it looks like it was done right.

Algon mechanical fuel injection for ford 427 MR

This is a mechanical fuel injection system made in the 1960's, hilborn style, constant flow - low pressure. It has 1 7/8" throttle bores, close to 48mm. This intake was also made with the throttle bores straight up, as opposed to at a 45 degree angle like this one. Probably a good start for an electrical fuel injection conversion. As there are no venturi's, it should flow better than 48IDA's, about 30% better.

new CNC venturi

Reduced to 730 CFM from 1425 CFM, much better signal.
