has different heads then normal 440 (not performance oriented) and also has short shaft transmission that won't work with a car and small block trans won't bolt up
oil pan has to be changed as well as pickup tube, motor mounts and manifolds

Life is an experiment
What motor do you have now? If it is a big block you are in business but if it isn't pull out some more money for a tranny.

the winnebago combo would've been a low compression motor so horsepower would've been pretty low, 300 or less. Pistons, cam, valves, intake and headers will change all that.
