Good point Bakerlite , having the engine centered does not necessarily put the whole engine in the center of the engine bay . However there is some room in the tunnel to get it close , or center with some creative clearancing , the RHD Big Block guys do it often .
Also the K set up I showed does have some adjustability , one should be able to find a happy compromise .
Alot depends on the trans you want to use .

First of I will say I was impressed on the quality and price of the HDK set up , and was considering this for my car , however as you state , the cost of importing puts it out of reach for some people .
