Transaxle?

Great idea!
Good luck

That's probably the biggest reason the small block is so popular in the As, as streeters especially; cuz we go around corners, a lot.
If you hang more weight out back,it seems like a good idea, but for a streeter, not so much. The tires are a limiting factor on the street, or rather the ever changing road surface is. To hang more weight out back with tires that already have their hands full,is, to my way of thinking,almost dangerous.
I have a 68 Barracuda fastback. It's a 108wb car and I think I have it up to 48% rear weight bias, or near to it. That puts a lot of strain on the cornering ability of the rear tires. She used to like stepping out, a lot. With 295s back there now, it is controllable. These tires fit into the factory wheel houses. I suppose I could put a bar on it, but Both I and the car have mellowed, and she hasn't spun out on me now for over 10 years. In fact with295s I can boil the hides in second gear and still run it around any corner that way.Second gear is good to 66 mph. 'Course I don't have the power or skilz to drift that. But I do ok.
Getting back to you and your 440-Scamp,unless you tub it and fit big meats back there,she may not be able to take advantage of a TA. And once the big meats go in there, she kindof losses her desire to corner, being more a point and shoot kindof girl. At least that is the feeling I got with 325/50-15s in my factory wheelhouses;which also fit,even lowered.OK, I admit it, I had to do a little bit of sheet metal adjusting with the BIG hammer.
The 325s also cornered oddly at slow speed, doing a little dance back there, that I found a little annoying. It was kindof the same as when I ran a spool. I didn't like it, and after about two weeks of that, I put the 295s back on, and saved the bad-boys for the track.
So as to the TA, sure great idea.But that won't be the end of it.
