GMC 478 cid V6 Engine

The biggest V6 Engine GMC every built is the 478 cid V6. This one was a pump

engine set up to run on natural gas. It came from a Texas Farm.

This engine is just about complete & mounted on a stand.

This would make a great engine in a pickup or one ton, and they came stock in the bigger GMCs.

The 478 has 235 horsepower @ 3200 rpms, and can put out 440 ft. lbs. of torque @ 1400 rpms.

This engine has the stanard round truck type flywheel housing and could be mated up with a

13 speed trans or Allision automatic.

I just SOLD this engine for $500, Sorry you waited too long.
