my brother bought a 56 customline victoria pretty cheap.the young kid that had it before had big plans to put a big scrub engine in it ... well ,you know the story the moron stripped it and sold the engine,trans ..etc. he cut the frame off at the firewall.my brother any comments will be wants to put it back to a real car and not the morphadite this guy had in mind.I told him any 55 or 56 frame would work preferably a 56 as there are a few differences in brakes. I know the crown and ragtop have the stronger x frame but the rest are the same right? he's gotten a lot of free advice from a lot of know it alls and I just want to make sure of my facts.by the way, he talked about putting in a 390 but i've convinced him he would be way happier with a yblock. any comments would be appreciated.
