Cosworth do some quality stroker pistons to be used with standard length rods - had no issues whatsoever with them on the stroker builds I have done.

Wiseco pistons and manley rods in mine,been very good although wiseco are quite noisey pistons when cold.

Thanks guys im not sure wiseco are for me then cold start noise will put me off or are all forged pistons a little noisy on start up because of heat expansion i did read that mahle only need 2 Thou running clearance and some needed 3 or even 4 Thou clearance

Every forged piston needs some clearance when cold Ian,if there isn't a little noise from cold then it will probably run tight and over heat when hot.

best to talk to your engine builder Ian about that
