340 swap-small block k frame or motor mounts?
a lot easier to clean paint and detail the front suspension and everything else in the swap by changing the k frame,you can build the whole front suspension,bolt the engine and transmission to it and lower the car body down on it with headers and all without a scratch to the firewall or inner fenders and it will look correct,and will be so much easier to clean and paint the engine bay and all the other pieces,thats just how I do it but the other ways will work alsobut what a pain installing headers around all that fresh paint just my.02 good luck and keep us posted how it goes either way
