it's weird how personally some people take it when someone else does something different with their car..
a GN with a small block is NOT just another G body- almost no other G body will have all the good suspension pieces that a GN has, and no other G body will have the 8.5 rear axle with the 3.42 gears that most small blocks love so very much. also, almost no other G body will have the good gas tank with the easily upgraded fuel pump if you want to run a later model efi motor like an LT1 or LS engine.
plus, the Regal/GN body is the cleanest and sleekest of all the G bodies- both interior and exterior- and has actual for real steel bumpers.
this particular car looks like a really clean install- but why not spend another $20 and get an upper radiator hose that actually fits? an upper hose for a late 80's/early 90's pickup with a 305 will clear the alternator and look like it was stock, you just need to get one for a truck without the HD cooling so that it has the smaller diameter hose.
