need to know what motor is a good swap-out for a 1988 ford E350 460 motor in a RV, need more power, current motor needs replaced
You could have a speed shop build you a big block stroker motor well over 500 cubic inches. Have them build it for towing and torque. Just a guess but you should be able to get 600 foot pounds or more!
Look for a 477 or 534 engine. https://en.wikipedia.org/wiki/Ford_Super_Duty_engine
