Hi nick and welcome. youve come to the right place to learn everything you will need to know with the rebuild.all you need to do is ask, there is a wealth of information and some very knowledgeable guys and girls here.
colour sounds great and would love to see some pics when you get them up.
the buicks sound like they could be worth playing with, maybe slot one in down the track im sure you can still get a fair amount of performance gear from the states to get them humming.
by the sounds of it you have all the hard work done mate, but are they ever really done
cheers
