The 1941 Plymouth Special Deluxe sedan Junkyard Find that I bought from the Brain-Melting Colorado Junkyard last fall now has the body off the frame and is awaiting a Lexus SC400 suspension subframe swap. After much debate about what engine/transmission combo to use in this Hell Project (the plan is to build it to Pikes Peak International Hill Climb specs, while retaining a grimy-looking rat-roddish character), I decided to go with the GM Vortec 4200 aka LL8 L6 engine, with turbocharging added, and that meant that I’d need to find a manual transmission that can withstand at least 400 ft-lbs of torque. Since the Vortec 4200 never came with a manual transmission, and the pseudo-bolt-on Aisin-based 5-speed out of the Solstice and Colorado can’t take the sort of power I’m hoping to get (thus forcing me to go the machine-shop bellhousing-adapter/custome-flywheel route), I was looking for a Borg-Warner T-56 out of a fourth-gen GM F-body, or maybe a Tremec TKO out of a fourth-gen Mustang.

Since my brain threw a code and made me buy the 1941 Plymouth Special Deluxe Junkyard Find yesterday, I need to choose a suitable modern engine and transmission combo for the thing. I’ve hired a rocket scientist and weirdo hot-rodder (the lunatic who built the Rocket Surgery Racing mid-engined Renault 4CV) to execute a chassis modernization program on the old Mopar, and I need to make my drivetrain choice ASAP. Suggestions? (Read More…)

When I first visited the Brain-Melting Colorado Junkyard earlier this year, I was keeping my eyes open for early postwar Plymouth sedans. I’ve always liked the look of those cars, with their sailing-ship hood ornaments and suicide doors. This yard has endless 1946-1950 Dodges, plus lots of Frazers, Willys, Kaisers, but not much in the way of Plymouths. However, if I expanded my search there to include late prewar Plymouths, this car jumps right out. (Read More…)
