very nice! I just don't know why so many people don't keep or give much credit to these motors. yes they cannot go 70 miles down the road in under 6 seconds but the sure have some grunt down low and seem to be very strong motors with nothing much wrong with them.and are fairly easy to get parts for and rebuild.and gas isn't all that bad either
so yes im sticking with my tractor motor!

There are a lot of things you can do to these motors to make them put out nearly as much horsepower as many stock AMC V8s, depending on your era. What they did to the later model 401s was almost criminal. Put HEI, a MC2150 and headers on a 4.2 and you have a nice bulletproof inline 6.
