Thanks guys. You all know the hours it takes to do silly, non standard stuff. Ali, Kettle's always warm. Dave, engine was fettled by Alan S and now has Cosworth Hi Comp pistons, Arrow 21mm Ti rods, full balance, 431 inlets and G exhausts, STM cam pullys, STM 48 tooth ally basket. Nothing to radical but it should give it the "S" character I was looking for. Rgds, Rob |
