318 Poly in an Early A Body?

I have a Poly out of a '66 Belvedere in my '67 D100 shorty. RV cam,Weiand 7503 single plane /500cfm Edelbrock,dual flowmasters. Scoots pretty well with the np435 4 speed.Plenty of room in the truck engine bay. I love the boat anchor, but would not put one in an A body. I love the HP 273 in my '65 Dart GT. All the power I need.
