Well, my only excuse is that I was bored whilst waiting for someone to collect an engine. Anyway - PB Engine Block with sump/oil/filter/pulleys/alt/w/pump etc : 80kg PB Head : 15kg Inlet manifold : 5kg Clutch/pressure plate assembly : 5kg Flywheel : 5kg Gearbox (2Y) : 35kg Other bits- KR Head complete : 25kg 6A block with piston/crank assembly only : 60kg All weights are approximate and may be the product of my imagination....
