Amc 304ci

Is it a ver easy conversion to put a AMC 304ci small block into a 1963 Rambler American 440. ? to replace that I6

Thanks.

i wouldnt do that IMO its a rare car and its original if u want more power get an offenhausere intake and holley 460 carb and then a header

if yoyu really want a 304 the you would have to replace and move the engine monunts, maby modify the tranny tunnel and maby modify the drive shaft, then with more power u might want to change the rear end but its all up to you
