You are correct. The JBL was designed for a Ford engine.

However, everyone thinks that it was the Small Block windsor series.

WRONG!!!

It was really designed for the Ford Cosworth DFL 3.9 liter engine. 540 hp and a really sweet power curve.

Or, for the criminally insane, a DFL Turbo motor (3.9 liters, horsepower dependant on boost knob, rumored to be in the 1000 bhp range for qualifying.)

Either of these engines are perfect in the JBL chassis and bolt right in. The threaded inserts are there in every chassis.

The mounts for a Hewland MVE-STA 6 speed to go along with these engines are also included in the chassis.

If you go to the JBL site and look at the 3D chassis drawings, you will see this engine configuration. They have been there since day one.


But it seems that everyone wants a BB and a toploader.

Go figure!!!!
