That is a valid point about the spring shackle.
The difference between the "off-road guys" and our old GM trucks is we have short stiff springs. Which means that forward or rearward movement is minimal on our old trucks compared to what you get from a long and soft spring on an off-road buggy.
I still say it's not worth changing shackle location.

Moving on,
Put new blower shaft seals in the forward end plate and installed the blower inlet housing, crossover pipe from turbo, starter, and a lower profile cam pulley.

At this point I'm done with the "hands on" part of this build. It's headed west.

So I now have lots of room in my garage to continue work on my truck at a faster pace than I have in the previous years, with some luck a much faster pace... (any progress is better than none)

Not sure if this thread will continue or if we'll see a new thread following the 53 GMC diesel conversion. I know I'm eager to see how it progresses from here.
