If it's for the later style engine without exposed push rod tubes, and the
offset (not inline) inlet and exhaust ports, I believe it's just
crankshaft, rods and oil pan. I don't believe the pistons are different,
but I don't have my reference material handy to state for sure. If your
oil pan already has the bulges in the shallow portion of the pan for the
additional throw of the larger engine, then it's just crank and rods and it
would be a good idea to use the duplex timing chain used on the larger
motors. The GT6 used only a single chain set -
