It was in a standard stock stockcar.
The rules permitted any 2 barrel carb with a 40mm restrictor plate under it and any ignition setup.
We ran a 2 barrel holley, but made a new bottom half that held the butterflies and was about 130mm tall that merged the 2 barrels into 40mm

For the ignition, we machined out the cam cover at the rear of the head so we could drive a distributer off the end of the cam.

The cam pulleys were made so we could fiddle the timing a little as we did not want to spend any money on cams.

It was raced for 2 seasons and then they changed the rules to read 'no multi valve engines' which banned us so we switched to a holden v6

The engine was stock internally and produced around 230hp with the restrictor which, at the time was faster than the competition which were running ea falcon motors and 4l ford and chev v8's.
