Monster 1600hp 872-cube swap for Rob Godfrey's Holden LH Torana

Monster 1600hp 872-cube swap for Rob Godfrey's Holden LH Torana

Rob Godfrey and mates are at the tail-end of a monster repower of his stunning LH Torana

The immaculate nitrous-assisted, big block-powered Holden had run into the bottom sevens with a 780-cube powerplant that came out of his Street Machine Of The Year-winning TOYTON HQ One-Tonner.

He recently advertised that engine combination and it was quickly snapped up, sending him on a USA buying spree that saw him secure one of the biggest-cube motors we’ve seen. The billet-block Sonny Leonard donk weighs in at a massive 872ci and makes over 1600hp in aspirated trim.

Holden LH ToranaIt’s a 5.3in-borespace block with a 5½in-stroke Bryant crank swinging 7.87in BME alloy rods and 16:1 Diamond pistons. The 15in cast heads are sealed with an O-ring/receiver groove and copper head gaskets, and run huge 2.6in titanium inlet valves and 1.95in stainless exhaust valves with Jesel 1.85:1 rockers, Smith Brothers ball-and-cup pushrods and Jesel keyway lifters. The intake is a custom deal with billet runners, topped by four split Dominator carbs fed by a MagnaFuel ProStar 500 pump and front header tank filled with C23. Adding to the mix is a four-stage nitrous system with two hardline and two softline kits.

It probably would have run a six-something with the old motor, but this one will take things a step further.”
