The GM v-6 is a great and durable engine, that packs a good punch with 'reasonable' economy. the bad part about swapping from a small-block to the v-8 is that the exhaust manifolds are different, (for obvious reasons), where small v8's would likely interchange.

Plus, small v's are in plentiful supply.
