Hi,

I have come to the point were I need to fit my pistons to my 351W block and need some advice please.

As I understand it the pistons are numbered 1-4 on the right hand (offside in the UK) with number 1 at the water pump end, and 5-8 on the left hand side with 5 at the water pump end.

The book I have says the pistons are notched and to put the notch facing forwards, but I have new pistons fitted which are unmarked so how do I determine which way round they should go.

The conrods are numbered 1-8 so do I make sure all the numbers are on the inside ( middle of the block) for both banks.

Thanks

Nick
