Interested in big block swap into 67 cuda

Most motor-home 440's have a passenger side water pump outlet , opposite of a passenger car , low compression . Usually they are low mileage .
Im doing a 505 stroker from a 73 Motor home 440
Heater blower motor may hit the valve cover .
Not a cheap swap , but a handful to drive :)
Ive seen them go for as low as $500 for engine and tranny , usually more .
