Vauxhall produced a Viva Magnum which had a slant 4 cylinder 1800 cc engine that was mated up to a Borg Warner TH180 3 speed automatic. The basic comparing I did with the 907 engine and the auto gearbox showed that it would not be that difficult to put an auto onto the 907. The cranks used for the 907 engine I believe are sourced from Vauxhall through the 70's. It is well documented that Lotus knew that it is the breathing and the head that gives an engine the performance so the head was developed on the slant 4, 2000 cc engine that found its way into Bedford CF vans and Vauxhall Victors etc of the late 60's and 70's. Then production of Lotus 907 engines with the wet sleeve got underway and the 4 valve head and double overhead cam fitted straight on. The engines share very closely the cylinder head studs, bore centres, crank, but so many other things changed with the oil pump and distrubuter. On the Vauxhall engine they put the distributor on top of the engine so you could see it and adjust the points! Lotus took a different approach. You can have the TH180 but the postage might be a killer, can do photos if you want. Tony H. Last edited on 09-03-2007 10:26 am by Tony Hollart |
