I've just about decided to abandon the original flat 6 and force a V8 into my '48 Plymouth Coupe. Got an '85 Chrysler 5th Avenue for a donor. Good running 318 with a 904 auto behind it. I'd also like to to use the rear end if possible. I haven't done the messuring yet (hopefully this weekend) but hope it will be wide enough. I'm wondering if anyone out there has done this or a similar swap. Any advice or warnings you might have could be helpful. I expect surprises along the way (never had a swap go really smoothly) but wouldn't mind avoiding some of the pitfalls.

I plan to keep the old flathead 6 as a future upgrade for my '38 sedan.
