Engine Swap in 1979 Estate Wagon

My son just bought his first car, 1979 Buick Estate Wagon. Awesome grocery getter. It has a 350 in it now but he bought a new 455 crate motor from a friend and wants to do a swap. Does anyone know what aftermarket exhaust manifolds will fit and what would be a nice intake and carb setup? The new 455 is just over stock on hp, nothing with a ton of hp.
Also, if anyone knows some places to find replacement doors, the bottoms on his are getting bad, it would be greatly appreciated.

 

Question is what were you doing for that one minute?

 

Too many groceries

 

How about shortie headers?
Regardless have a great time with it.
I remember big block Buick big cars racing hard on the street 80s-early 90s.

 

And here is another option while doing mods

Yeeeeeeee Haw!!!

 

I do kinda like this Oldsmobile with a Buick 455 in it though, all hard work is done.

I like this one

 

I wonder how hard it would be to change trim to make that Olds into a Buick....find a donor car in junkyard......

 

Great minds think alike,I was wondering the same thing,already has the rims and drivetrain : )
Take off the 455 emblems and it would make a sneaky sleeper!

 

All cool cars to me

 

Just needs more grunt than the 205 hp it came with

 

13 pictures Fritzee...and not one shot under the hood!

Not bad for the money tho, I bet $3500 laid on the hood would buy it!

 

Any progress??
