Now it’s rocking a monster 565-cube big-block Chev stuffed with Manley running gear and topped with AFR heads and a 1000hp 4150 carby. The motor is backed by a tough TH400 trans and a nine-inch 35-spline Strange rear end.
Jim originally hails from Sydney and had the car running and driving up there before moving to Melbourne about six months ago. Since then his fuel system went kaput, so he had the guys at MPW install a new fuel cell with Holley pumps. After a bit of fine-tuning on the dyno, the Monaro made more power than ever; the rollers saw 540rwhp pretty consistently.
But Jim isn’t finished yet! Next item on the to-do list is to swap out the locked dizzy for a programmable timing system, which should liberate a few more ponies and improve driveability. Eventually Jim wants to go ProCharged and EFI, but that’s a long way down the track. For now he’s just keen to get out and drive the thing.
