I upgraded to hydroboost a few years ago. Pretty much stock everything and no issues. I did get the pump with 2 return lines so that I don't have to T the returns together, but there isn't a difference in cost.
Well, I've since LS swapped it, but I believe it was an early 80's 3500. I'm certain it's in my build thread. Anything that came stock with hydroboost will have it though. All of those pumps will fit our brackets.What's the pump from Josh? I'm gathering parts for the upgrade.
