The Intermediate Rover cover is off of the GEMS engines(1996-1999, BAE era), not the later Thor Motronic (1999-2002, the BMW era). The earlier covers still had spur gear pumps and the later covers didn't have distributor holes however it is theortically possible to use an Series II cam sensor and flying magnet setup since the LC2 setup is a metal shield interupter hall effect sync switch and the Series II is a flying magnet hall effect sync switch.
The 215 (3.5, 3.9, 4.2, 4.0, 4.6 Liter Rover dirivatives) are not Nailheads but the first generation Buick Small Block. The original Buick V6 was based off of this designed and as the SBB evolved the V6 adapted along with it to share production parts. The 215 looked like a Nailhead to tie into the larger Buick engines of the time with thier characteristic valve covers but the distributor was in the front not the back like a Nailhead.
I started doing this as an engineering exercise off of Kendall's experiments with this on his Stage II "Second Hand Six" I thought the gerotor design with its divorced oil pump drive releived the strain on the front cam bearing and is a more efficient pump that holds its clearances better. They have been used for years on pretty much all GM transmissions and Mo'Par engines. Lately they have started making billet gerotor units for the SBC and BBC to deal with needs of the supersized stroker motors and tall deck blocks. This however became a nessecity when I discovered that the V6 will sit so far back in the engine bay of my '64 Riviera that the stock spur gear oil pump setup would conflict with the engine cross member and since I was already on this path and didn't want to notch my frame I decided to fully commit to this project.
Expect results in July, I am also retrofitting an L67 supercharged ECM and harness to run the engine using OBDII controls and a flash based tuner.
