Thread: Any type of speed equip, for plymouth flathead six(1933,P 12)

Tweet

Just got a 1933 Plymouth PC 5 window coupe,All there never been hot rodded,has rust in the rear body, below the rumble seat.looking to see if there is any speed equipt. for engine.

Nice find.

I spent a little time with stock 40s and early 50s Dodge FH 6s. One was in a 49 with the hydra drive (can't think of the actual name they had for it... Fluid Drive I think), the other a 52 1/2 ton PU. And if I remember right ther were a little larger in CI... longer stroked maybe, but maybe not, than your 33.

I have never heard of any after market... but really have never looked. BUT I do know this. The old FH chrysler 6s were long stroked and while they could pull 100% at 1800 rpm for 40 years they did not handle high revs (by high I mean over like 3200). Bottom ends simply flew apart (lube issues maybe???). Dad's 52 basically topped out at 50 mph or so... but it could pull a semi at 20 (and did once!.. was hard on the clutch though)

I'll be watching this as I'm curious too. I wonder what MOPAR has (Direct Connection... but they may have changed their name by now). Been a while.

Fluid drive is what it was actully called, slushomatic was the more common name

There's lots of stuff for the Mopar flat six. Check out this link and go to the 'Mopar' section.

There is a fix for the oiling problem. The crank needs to be cross-drilled. Do this and get a high-volume oil pump and you should be good for at least 5000 rpm - more if you prep the bottom end properly.
