Just joining today. Was wondering if anyone has or is building a 1934 Plymouth PE coupe. If so, have you installed a 518A overdrive transmission in it? How did that work out?

My thoughts are putting a modern driveline in an atique like that is a great idea if your making a driver out of it.
To keep it antique I would keep it as OE as possible.
The 518a may not fit under the tranny tunnel, so mods may become necessary. Try lifting with a floor jack, up under the trans tunnel just to eyeball it to see how well it will fit.
The 518A is a great upgrade, but The atiquated rear is not so much.
I would think using a new rear and the 518 with a SBchrysler like a 5.9 would be a sweet deal for that car.
Time to bust out the measuring tape and a note pad.
Fact is stranger than Fiction

Thanks for the suggestion. It currently has a 318 with a 727 tranny, an 8" Ford rear with 355 gear. I need another high gear. I don't have a 518 transmission yet but was concerned about the fit going through the cross member and other issues someone may know about.

I think the 518 is basically a 727 with an overdrive. You will need to research how to make the shifting work - just google it and you will get many results to show you how its done.
