Africa , Team Lotus entered two 43 cars with the H16 BRM engines. The 43 was certainly not the car for Monaco so two 33s were entered, Clark with the 2000cc V8 engine he used during a great part of the 1966 season(33-R14), and as only one such engine was at disposal, G.Hill, ex BRM driver inherited a 2000-V8 BRM engine, in fact the combination used by Arundell the preceding season (33-R11).

Why not both with BRMs or both with C-Cs?
Was it because each knew the engine charactertics of the respective engines?

It was difficult to swap back-and-forth with a BRM V8, even if they used a gearbox with the same right-hand linkage as the ZF; the water-pipes were different sizes, for instance.
So they put a readily-available BRM V8 into R11 to give Pete Arundell a chance to get in the races, and that was what Graham Hill was stuck with in early 1967 when he replaced Pete.

Different CoG??
Presumably that would be the same for the Lotus 33??

Wonder if there was some ulterior motive in ACBC's comments...............

A period article about Ian Raby's Brabham (which he converted from Climax to BRM) said that BRMs need larger diameter oil & water pipes (e.g. they rely on higher flow rates).
Maybe ACBC felt that it would be hard to fit suitable sized pipes (plus radiators & tanks) in the confines of a 25 tub.
The change of gearbox (no one else had ZFs) could have more effect on the c of g than the engine type - the crank centerline being determined by the gearbox input shaft - the engines are so very similar that it is hard to imagine there is a significant difference in their weight distribution.

Did Parnell run Hewlands with their BRMs? The engines certainly looked to be mounted as low in their 25s as the Climax in the works cars - maybe the ZF was lighter.

I think that Parnell used Hewlands throughout 1964, the only exception being the Austrian Grand Prix where Amon drove R4 on loan from the factory with Climax and ZF. Two weeks later, at Monza, Parnell had bought the car and fitted a BRM and Hewland.Originally posted by Macca
Regarding what gearboxes the Parnell Racing 25s used - I found this shot of Hailwood's car at the European GP at Brands in 1964.
