I am trying to decide on buying one and putting it in my 85 in a few months since the 305 that I have in it now has a lot of miles. But then again I am going to get a manifold, carb and updated to MSD already and I would like to just get a short block and do the rest. I think for the 48 I would like to build my own I don't know.... Thanks Twitch for that site I will check it out.
