the vibe and colours are there for me but the type comes up a bit short for me, either hand drawn (as always) or smaller (the 23 & 24 may are really too big) and keep all the text at the same hor. & vert. same font with 4 different distortions
as far lt-1 vettes, there were something a short run made in the 71-73 production with aluminum blocks but the standard small block 350 was the norm (I don't know about modern LT-1s)
