bx is 300 plus a 500 diff which sould be ok.

Engine was a xer crank at 400, some 200 quid steel rods, 4-500 in omega pistons, a 200 head gasket usual bottom end gaskets, oil pump, replacement block and sump.

think the head was on oversize inlets. beyond that, mnifolds etc will be fine.

They have a shedload of spares and a lot of friends tho!
