Mark Drew has long had an affliction for building quick street V8’s, many of them being Holden Torana’s.
This particular LH was originally built in a mere 5 weeks and ran a best time of 9.41 at 146mph in naturally aspirated from a 434-cube small block chev.
After getting a taste of LS boost from his wife’s wild HR Holden, Mark decided that was a good enough route to travel down in the lighter weight Torana.
The body might look a bit rough, but check out that engine bay, turbo’s what turbos? Mark has done a stellar job of making sure the bay is as simple as possible. The LSX bullet features a Dart block and cylinder heads with boost supplied from twin Borg Warner turbos and a Holley EFI E85 fuel setup. These were the first pass under boost on wastegate pressure only.
