Question type: Maintenance & Repair

I have a 1974 chevy c20 with a 350. The
truck starts great, revs great, even goes
down the road great with no miss. Problem
is its got no power, even going up a
moderate hill you have to floor it and still
loose speed. Its got new plugs, new plug
wires, a new hei distributor. What can cause
the lack of power?

Lack of power may be low compression on engine,do a compression check on it,all so check the timing.
