LS Swap '65 Valiant

I'll state the same thing here that I state everywhere....
IF Ma Mopar made shitty engines or IF they were hard to find, I'd understand ideas like these.
That is not the case though. Not even close.
People see these cheap junkyard LS engines and think they can swap them in an old car and go fast for minimal bucks.
IF you are a master fabricator, it can be done on a tight budget but you're looking at custom oil pans, headers, engine mounts. wiring and possible computer electronics. These early A body cars are cramped so power steering is out. The transmission tunnels are tiny so you're looking at modifications to fit a modern transmission.
This is like buying a hat that is too small, then going to a surgeon to have your head surgically reduced to fit the hat.
A stroked 360 will make more power than you can hook up on the street and those engines fit easily. There are headers available that fit the stock chassis.
This isn't Cuba, man...Cross breeding is not necessary here.
