Re: [AMC-List] 258 6cyl swap into 63american convertible

["Swygert, Francis G MSgt 436 CES/CECM" <Francis.Swygert3@xxxxxxxxxxxx>]

The Aussie EFI intake with the runners curved over the valve cover MIGHT
fit in a 58-63 American without removing the hump, the carb intake
definitely won't. There's only a couple inches difference (estimating
from the pics), but that's enough! Take the outer barrel off the carb
intake and it would fit. The left to right placement of the two barrel
carbs is what I found that prevented using a modern four cylinder also.
I didn't find one that placed the barrels front to back and a bit closer
to the head. Since they all used progressive linkage the side to side
mount works better. The early 2.3L Ford used progressive linkage, but I
don't recall if the barrels are side to side or front to back. I do
recall the intake doesn't stick out as far as later, better flowing
ones. 

The early American engine bay is tighter side to side than the early
Mustang/Falcon/64-69 American. That engine barely fits in a Mustang bay.
The header shown on the Ford Six site won't fit either. I'll haveto
check, but I seem to recall the engine bay as being 23-24" between the
suspension mounting points. It gets wider above the upper control arm
mounting points, but the distance between the humps is only a couple
inches more at the peak of the hump. The humps stick out at least two
inches from the rest of the inner fender panels. Cut the humps at just
the right spot and you can weld the inner panel to the outer without
adding metal (I THINK...), but I'd add a piece anyway for strength.

i can't stop thinking about the ford swap!

you mentioned side clearance vs. the ford's cast-in intake.  would the
ford aussie 12-port head and intake
http://classicinlines.com/proddetail.asp?prod=OZ%2D250%2D2VH
have adequate clearance?  from what i can find, the argentinian head
seen here http://classicinlines.com/categories.asp?cat=48 but the
intake is definitely snarkier, though it sticks out a little farther
too.

another good view of the aussie head is about 1/2 way down here
http://classicinlines.com/orderonline.asp and notice it's on a 200.
making the assumption that the ford '2.77' is a warner t96, the
'64-'80 200 is the largest block that'll take the '60-5 bell and bolt
straight to the amc tranny.  '80-up 200s got a modified sbf pattern.

after the engine is snugged into place and running well, you could
step up to a t5 with a late '70s 'srod' bell, redrilled.

a toploader would bolt straight up to the '67 - mid '70s bell, and a
tremec to the srod one, but i've assumed they'd be too big for the
tunnel.  however - didn't these cars use the iron warner auto before
the aluminum ones became available?

[i got the bellhousing info from the 'chainsaw al' pages mentioned at
fordsix.com, but they're long gone now.  i saved the manual tranny
swap pg but the adapter pg was already down and neither al nor the co
he sold his biz to responded to inquiries.  a real shame as he
explicitly mentions a 2.77 - t5 adapter]

more radical possibilities are the crossflow head adapted to a 200
here http://www.fordsix.com/tech/engine/crossflow/crossflow.php
or an entire aussie crossflow engine as detailed here
http://www.fordsix.com/tech/engine/crossflow/xflow.php
scroll almost 2/3 down to "Assembled and almost ready" to see the
excellent efi intake in the shop, and at the bottom for it in the car.
imagine how that'd look under the hood of a bathtub nash!

he says the flywheel is the same as the us 250 but i didn't catch
anything on the bellhousing pattern.  i -presume- it's the same sbf
also.
