Always wanted to build a mid-engined Matador fastback to convey it's AMX/3 heritage but ever since they passed the no emission control device tampering law for any car '74-up I've been choosing older AMC cars to keep my hobby more acceptable in that regard.

So when I found this '69 Rebel coupe, I knew what I wanted to do next: REBEL/M-XRV8

Starting out with a junk car so no full pics of the body until it begins to look better.

First priority is to make it run and drive.

Here's a few pics of the work in progress:



The '65 solid main 327 XRV8 engine is set back 30", as far forward in the cabin as possible.



The 'X' shape removable plate engine mount construction provides resistance against spherical forces of inertia for crash safety, directs road wheel load more directly to center of gravity, allows removal of engine from underneath and provides space for fabricating a custom 180 degree header system.

Piques my interest as well, sparking fresh new things to study.

I've almost got all the basic components installed to make it run, as an engine stand at least.

Two more pics:



Took me two weeks just to make the custom driveshaft (during Hurricane Harvey -we got wind and  rain here) It's made using a Rambler Marlin/Classic 'cardan joint' cut in half with 1/8" wall 3" tube spliced in between.



With such a short driveshaft, to get acceptable driveshaft alignment, the rear axle must be raised.

This dictates the car's ride height must be 'slammed'; very low to the ground.

The engine and trans are mounted high enough so they won't scrape the ground if the car drags it's belly over a railroad track crossing.

I like the idea of it hugging the ground,
but short wheelbase Jeep guys deal with the large output to axle elevation difference by using a double cardan joint at the transmission end,
that way the rear joint angle doesn't have to match the front joint angle,
and the axle can be more or less pointed up at the back of the double cardan.

All that said, I'd probably like to see the build low to the ground anyway Clap

Keeping it all AMC, I chose to mount a (new) 15 gallon Jeep CJ gas tank 'Mustang style' in the trunk.

The tank is customized with re-arranged fittings for longitudinal placement, which allows plenty of room on either side for rear exit exhaust pipes (wide stock Rebel tank forces pipes outside the rear frame rails)

The tank has a custom sump/drag race style rear exit fuel line port underneath to feed nearby 72 gph 5psi. electric fuel pump that will draw it's 12 volts from trunk mounted battery above.

The driver and passenger seats will be only slightly forward of where the back seat used to be (which oddly enough may even improve getting in and out of the car)...

I just finished re-doing a spare stock brass Matador radiator & plan to mount it 'Pantera style' up front. (using thin gauge steel tubes to go the distance between the engine and the radiator)

I plan to duct electric fan driven radiator heat 'Pantera style' up through reverse scoops in the hood... -confirmed by noticing hood design of '66 AMX II showcar (the '67 Rebel's prototype)

Sorry guess I did not say it right & I need to show a better pic of the driveshaft... as I understand it, by my studies, nothing should be lined up perfectly straight to avoid undesirable forms of gyroscopic effect which could make the car very unsafe... everything is slightly offset to the passenger side & the driveshaft is almost straight but has a slight angled downward slope to the pinion yoke (with a u-joint on each end)

I think the '67-'69 Rebel 2dr coupe body style looks great 'slammed' on the ground...

Thanks in advance,

Thank you both for your positive encouragements.

Mid-engined Grant Rebel SST Funny Car is most definitely on the inspiration list but no this car won't have a funny car body on frame style construction.



(thanks to whoever posted that pic on Internet)

Grant Rebel SST used AM's iron case automatic transmission. None of the historical articles on the car contain info. telling about transmission failure. Rather, we have at least one example of an AM WG iron case automatic that successfully withstood 1000 hp & 9000 rpm action in actual Funny Car competition!

I'll be using this '65 Marlin AM WG AS2 10B auto. trans. in this car:



Here's another quick pic of the driveshaft (stock Marlin/Classic cardan joint was cut in half, then 3" tube spliced in)



As your brother in the AM vintage car hobby, IMO, we need to concentrate more on ethanol compatible fuel system components to keep our vintage AMCs from falling behind into oblivion.

Thank you AMC Forum and more AM power to you all with your own AMC projects.

Still saving up money and acquiring parts...
              
 ...I was looking for high lift springs, but look at what I just found on eBay!

                      HIGH PERFORMANCE VALVE SPRING RETAINERS FOR RAMBLER V8!


*I'm not recommending anyone should use these: they're aluminum... and that's why they're still in an unopened package!

(aluminum valve spring retainers were a short lived fad in the early seventies; IMO since aluminum expansion rate is greater than the valve springs, they're sure to chafe and put tiny metal flakes in the engine oil etc)

-just posted the pic for grins... rare sight to to see vintage hop up parts for Rambler V8
