81, fleetwood superior -alright ive come to the conclusion the 368 4 barrels gotta go. eats gas and has no power. if i wanted to make this hearse a sleeper which caddy big block would be the best choice? not wanting to go blower and all that but looking into ideas. wanna be able to have a little fun with it. and which trans to go with that engine and what rear end from what year to go with it. I'd also like this make this engine simple. fuck all these vacuum lines and my state dont have emission bullshit

I put a '74 472 in my '82. You have to use parts from the 368 like the oil pan and sup pump. She has more power and drinks a lot more gas, but she's not the rocket you would think that a 6.0L to a 7.7L would be. Also the '80's bodies are so small and tight that you would have to have custom headers made. Regular 472 block hugger headers won't fit. And the 472 and 368 exhaust ports are differant. One of my Exhaust manifolds broke on the 472, so the mechanic used one of the 368 manifolds. One has square ports and the other has rectangler ports.
Just letting you know there are many things that go with the transplant.

My pet project is usually mopar 318s so I dunno alot about caddy engines, but I do know that your asking for alot of work!
yours is either a 4.5 or a 4.9 not a 4.6. had to pick on ya.

not an echo. he said it was either 4.5 or 4.9 I was just clarifying.
And I personly don't care if it's faster than my transplant. You have made that point a couple of post back, no need to say it more than once.
In my previous post I meant to say "at least it is a step above the 4.1" ( no offence Ryan)
