Yeah it seems a little ridiculous. Clifford manifolds are already produced with the added manifold surface area for the bungs to be drilled. Basically its drilling and adding some injectors/rails/fuelpump and they are charging out the wazoooooo. I could see that price if they had to fabricate something new.....but they dont have to produce anything new for it. Its basically bolt on GM fuel injection and some software to run it.
You would think that Clifford would attempt to discourage people from doing a Junkyard GM setup with a little more competatively priced setup........
