small block heads for a long distance cruiser

Drop in a good used 5.9 magnum. Use a magnum bolt pattern intake or have the magnum heads redrilled to LA pattern. Headers, good 2.5 inch dual exhaust and a decent tune up. Itll run great and be north of 300HP for cheap! I've bought a few 5.9 engines in great running condition for $600. Your 360 LA oil pan, distributor, valve covers, timing cover, etc all fit. The intake is the only issue you have and it's an easy issue to solve.
