The 6bt is too long by about 6" in a FFPW, the 4bt would be just right. I have a 4bt in my Jeep and it works great. I swapped a Detroit diesel 453 into my 57 FFPW but that is not finished. I have driven it and it is VERY loud, so much so that it will only be for very short trips. If you decide on a 4bt, also decide on what transmission and buy the engine accordingly. For instance if you want a GM manual trans then get a 4bt that was mated to a GM manual trans. Don't get a 4bt that was mated to an automatic because the parts to change it over to a manual application are very pricey.
