Sometimes people throw out a plan to see how it floats, or to get some attention...and move on. Seeing as how a standard V8 Vega rates a 2/10 on the fabrication-challenge scale, and the idea discussed would be like a 5/10, it's unlikely anything would ever come of it from that end (feel welcome to prove me wrong...).

In the meanwhile it's fun to imagine and these plans could apply to a wide range of bizarre conceptions.

Another potential layout is the V-drive such as used in wheelie cars. The engine could be placed longitudinally with a normal transmission, low, backwards just in front of the rear axle instead of above as in the above application, with a shaft running forward to a boat v-drive or fabricated box without the included angle, mounted diagonally (as seen from behind) so that the second driveshaft runs alongside the engine to a diff with the center offset (axles would have to be different diameters to not torque-steer). The live-axle is of-course flipped for correct rotation at the ground. Advantages are low-cost and strength, and potential for eye-appealing mods such as huge induction and boat headers. Disadvantage is that the engine would sit a little high for a sports car, and you're ridin' with a transmission at your hip. I once did a bit of work on such a setup only the engine was normal-faced above and ahead of the axle with what I called the "transfer box" at the rear (an aluminum case containg a pair of 7" gears from a truck trans). Was to be for a street-wheelstander El Camino but when life got in the way it all wound up in the corner.

The more you dig into this, the better it gets. Also, don't forget about the Ford Taurus all-alloy V-6, 3-liter FWD 5-speed. Neat package. Strong. Light. All-aluminum motor built by Yamaha, not sure about transaxle.
Transaxle is Mazda-sourced. I had a 91 Taurus SHO with a 5-speed and the rod-shifter upgrade that I mobbed around a little. Fun car for how heavy it was. Here's a good example of what you're talking about owned by Jay Leno.

FWIW, compared to modern longitudinal 5-speeds like a T-5, the SHO shifted about as precisely as an old SM420. It was still a blast once the butterflies in the intake opened above 4k.

AutoGear V8 fieros are mid engine and standard rotation.

essentially remove the diff section of the T-A with the 4cyl (or V6). Then Bolt the Diff section to the back of your SBC (up to the LT1, not sure about LS motors). Dunk in the powerplant, connect the ancillaries and use a small 4 core radiator and go harass the neighborhood. There was one guy in PA that had a silver fiero with an automatic T-A and a nitrous'd SBC that was deep in the 10s at like 128mph; Paul something-or-other. I think he was in 'Super Pro' with it.
This was not a factory stock T-A, but it shows what this combination is capable of

Are those reverse rotation boat cam V8's??. Mounted behind the trans-axle?

Yes it does, my pantera scared the crap out of me at anything over 100 MPH. In stock form the front end would lift and the body acted like a wing, the rear would get light also. I solved all those problems by adding an air dam in the front (it also solved the cooling issues panteras had by forcing air throuh the rad). I bought a rear wing from Hall pantera that planted the rear.

techinspector1 I think the Chevette was rear wheel drive. You may be thinking of the Citation. I have been told that the IFS of the Chevette is very close to the IFS of the Fiero, so maybe GM used the Citation FWD transaxle in the rear of the Fiero and the Chevette IFS in the front of the Fiero. I don't know for sure.
05-02-2013 07:43 PM
MARTINSR Ahhhhh, Chevette, it's the Chevette front transaxle and suspension mounted in the back.

Brian
05-02-2013 07:41 PM
MARTINSR But the Fiero rear is simply a transaxle from the little front drive.....Chevy.....crap I can't remember the name, CRAP. Anyway that is all it was, suspension and all! It literally had the same spindles with a little tie rod going over to the frame to adjust the toe. So you could narrow it easy enough.

Vega rear 53.6"
Fiero rear 59.3"
A fellow might be able to make up the 2.85" difference per side with some offset wheels like GM did on the Eldorado and Toronado FWD cars.
