Ya there is an M1 but it's up around 3 hundred. Money is an object in my world and I can't justify spending that kind of money on an intake for a 4x4. I have a mental cap that is around 150,but I'd prefer the 80-100 dollar range. I've been looking at the heads and I think I can drill them for LA and still retain the Magnum holes as well. That way I can do either. I am going to convert the EFI manifold and see how it works. I have all the stuff to do it so I might as well give it a shot.
