Re: [AMC-List] rambler hot rod

["Jim Blair" <carnuck@xxxxxxxxxxx>]

A: I didn't know it was a 6 till today. I think a D44 from an FSJ would be 
just the ticket, along with whatever trans and a Dana 20 tcase (short 
adapters are available. Maybe a BW from a V8 with 6 cyl bell and FMX to D20 
adapter?) I have seen Mitsubishi 6 cyl diesels in Dodges, but not Nissan 
ones. IH ran the Nissan diesel with std trans and 727 auto as well as CJ10s 
and overseas Jtrucks.
   Auto trans wouldn't need to be run backwards with the tcase gutted to run 
the front.

" A: Now that I see the original post, some things are a little
clearer.
"
" My take:
" Front axle should be a Dana 60 (or maybe 9". Dana 44 if not
too much power
" is made) flipped from a 4x4. D30 won't take much power to kill
if it's the
" only drive axle.

imho a d60 would be monstrous overkill for a little light track
car.  i
agree about the d30 though.

" OR
" Rear motor facing forwards using Jeep 727 trans and NP208
tcase from a CJ10
" tug shifted to 4 high (I drove my '83 Cherokee for several
months this way
" with no rear driveshaft) The one from a tug is built stronger
than a regular
" Jeep one (wider chain, etc) as they are used to move planes on
the tarmack
" with a Nissan diesel.

the nissan was also available in dodge pickups about then, so i
wouldn't be surprised if the t/c is a np208d.  one of the tricks
for
beefing a jeep nv231 t/c is to use 231d dodge sprockets and
chain, as
they're wider then the 231j parts.

i don't think an auto trans would take kindly to being spun
backeards
though - unless you're talking about projecting fwd of the axle
and
driving it from the front.  but if you're thinking of this --

" Balancing the weight/power will be the toughest part. Too bad
the Tornado
" didn't come with a Nailhead motor. Then you could use an FSJ
adapter ring
" from a TH400 to bolt it up!

-- then why not project the driveline back behind the rear axle
and
use a t/c to reverse direction and drive the axle from the back?

offset the engine/tranny to the right and place them so the
tailshaft
is about over [or under?] the axle.  strip the t/c of everything
it
doesn't need, low range for a start.  maybe make a custom case
with
only the sprockets and chain.  divorce it from the tranny and
put it
on short driveshafts from the tranny and to the axle.

imho the axle would work best if the diff were also offset, to
the
left.  start with something like a narrow-track cj quadratrac
d44;
it's probably offset the wrong way so pull the tubes off and
swap
them.  i'd also suggest pressing them back onto a high-pinion
ford
front chuck; hypoid r&p are stronger pushing than pulling.  or
just
call one of the custom axle places like currie and hand 'em your
specs.

or you could use/make a d44-based irs, like the jag or corvette
[or
viper?].

" So I've been thinking and drawing over the last year or so
ideas
" for a rambler hot rod. Six cylinder, sort of "old style" rod,
" track-roadster-ish. Two seats. Open wheels (motorcycle-type
" fenders), no doors, no roof.
"
" I really want a mid-engine car, but Hallibrand transaxles are
" out of my range, but I think I've come up with a scheme for a
" rear engine, front drive car, using a jeep or eagle front
axle.

wasn't there a relatively-recent corvette that had a transaxle?
they
oughta be showing up in junkyards...

just noodling...  but what about a cord-like layout, where the
driver
and passenger sit mostly behind the engine but almost between
the rear
wheels?

" I do have this Navarro-built turbo six... but it's not a
" requirement, and might not be appropriate to run in the
street.

i think if you don't get weight/power distribution right, this
engine
would be a big mistake.  likely a handful even if you do get it
right...

" The big chunks lay out OK for a 104" plus or minus wheelbase.

the cord approach would probably shoot the wheelbase up.  it'd
be
novel though!  thought: doesn't the jeep liberty [ugh] have ifs?

" Big HP isn't a goal, so driveline strength isn't an issue. It
" goes without saying it'll be all AMC.

you'd have to make a custom bellhousing adapter, but a midengine
kitcar-modified corvair transaxle/irs might fit the bill.  iirc
it's
saginaw made, so i'd guess perhaps 250 ft-lbs for a design
limit.

" I figure standard hotrod kitcar junk for the rest of it.
Weight
" distribution won't be all that great (heavy rear), eh, I'm
" not racing.
