You should see Slowy's setup - accessories swapped left-right / top-bottom, custom this and that, still a work in progress. I'm sure there's a Ford joke there somewhere...
I'm fitting an LS3 into a Harrison. There was a fair bit of stuffing around getting the right PS mount. It's all sorted now. Your welcome to come around and check out the alternator and PS pump alignment. I'm in the Eastern suburbs.
