Do you mean Wisbech American Street & Performance? If so the phone no is 01945588091, but Chris is on holiday at the moment so it will be a week or so before he gets back to you.
I was on the phone this afternoon to the guy who looks after my Overfinch and he was saying that I should have a look at Hemi 6.1 units and that Street and Performance might be a place to start.
