is that original paint? (besides the artwork/logo, that is) Most 2 tone trucks that era had the top color more than just on the roof, it extended to the upper bodyline. My 85 is same 2 colors as yours. wanting to redo it (probably stock colors) but not sure I want to put the trim back on (mainly because I am missing some) and looking for a decent way to make the break between colors, without hiding it under that trim. I'm keeping the /6 in mine, have a fresh one on teh stand, with a few improvements from stock. I like the idea of a Poly head 318. It's different but should bolt up the same as the newer LA series engine. Mounts and trans bolt pattern-wise, anyways. and it seems there are more "hop up" parts for the Poly, and less of a "laughingstock" engine, than the 318 that would have been stock, in those years.... and I'm not complaining, I've had plenty of 67-up 318s over the years/ personally, I love em.....
