Hello, I have a 78 C10. I have a "mock up" 6.0 long block sitting in the frame using Tin Works Fabrication motor mounts. The engine sits nice in the frame and has about 4 degrees of rear tilt, like the factory LS trucks that I checked. The 4L80 and original drive shaft fit without altering. The engine is all the way forward (mounts allow engine to slide). The motor looks like it belongs right where it is but I don't think a very tall valve cover will fit. I want to run the adapter that hides the coils and accepts standard small block Chevy valve covers. With this set up the overall height is 5". Is anybody running something similar? The valve covers I want to run are ProForm 141-924 and the adapter is Sum-440690. Anybody running this set up? pics? Thanks.
