Thanks for the warning Ron, I will ring them tomorrow. Bill, no its just a full house Gurney Weslake with dry sump pump etc, we have just kept everything tight to the front of the engine to maintain its position ( in a GTD ) without having to modify bulkhead etc. Plan is to mount it directly in front of the left hand cylinder head, but the v belt alignment has been moved back closer to the block making things tight ! Thanks guys for all input, Frank
