thanks guys for your help really appreciated. I really need to find one, for the second engine for my kit car the one in it at the moment is a m44 and she has star ship mileage. I like the m42 and all its slightly self destructing problems, its a good strong block and forged internals, I feel a little gentle force induction coming, not much just a little. Ater a bit of beefing up of course!!!!
