The 24 Hours of Lemons allows real people to live out their (slightly tempered) racing dreams. But if you want to race a classic American muscle car–think early V8 power and rear-wheel drive–how do you start such a build for hundreds and not thousands? 

Jim Sayre of Valve Tap Racing followed the Mopar muscle car pedigree to its logical (and …

My grandfather had a 76, Brown with Tan interior and vinyl top.  Was no match for my aunt's Cuda in a straight line but it was way more comfy..  He was a Mopar Man, retired from Ma Mopar after 30 years.  The Cordoba was his retirement car.

I noted in the video that he refers to it as a "Small Chrysler ".  That made me chuckle!!!

Our peculiar habit of stuffing our corpulent bodies into tiny shoeboxes on wheels had yet to manifest itself.  Many cars we think of as large today were, in their time, sold as "personal size" cars.

They were small "ish" compared to their earlier bredren..  This is what my Grandpa's Cordoba replaced, 1972 Chrysler New Yorker Brougham. That thing had it's own zip code.

Having spent many hours riding around with a friend in his 400 ci Cordoba, I can tell you they were absolutely faster than you'd expect. Not fast like a built Camaro, but fast compared to most of the emissions-laden junk we stop light raced in the 1980s. Remove the Lean Burn system and add some exhaust and a cam, and Bob's your uncle.

Richard Petty's last Mopar race car was a Dodge Magnum, which was a sister car to the Cordoba, so there's sort of a race heritage...

I had a Magnum with a 400 big block.  Ended up donating it to charity.  Wish I hadn't, now, but gas was comparatively cheap then...

I was given a Magnum with a 360, I think.  At the time I really didn't like it, too big, too metallic brown, automatic.  But looking back on it now, and if the internet had been around to show how to mess with it, I would take it back.

I think I would rather have this one. Think of how much you could haul in that trunk.

In 1979 they made a Chrysler 300 off the Córdoba. Came with a 195 hp 360.

I'm not a hardcore Mopar guy but I seem to remember that the 400 was just a B and not an RB so it had a shorter deck than the other big uns.  But it had a larger bore than even the 440.  I guess the short deck height means that a 440 crank won't clear?  I assume.  Seems you could make a really big un.

Just think how many votes you could stuff in the trunk on Election Day

The mains on the 440 crank have to be turned down to fit the 400 block.  There is a good chance the counterbalance weights and/or the block will need massaging, as well.  This will get you 451 cubes, which isn't all that much, but the lighter block, less reciprocating mass, and more compact size will net quite a few benefits aside from displacement.  Offset grinding the rod journals and using Chevy rods with custom pistons gives even more displacement, but has tradeoffs, as well.

Honestly, the biggest limit for BBM power is in the stock heads.

You can get a stroker kit these days to turn a 400 into a 512.  A few years ago on the Hot Rod Garage TV show they did a build on a 400 that's in a 1965 Plymouth Fury station wagon, it looked like a relatively cheap way to get a lot of horsepower.

Seriously, I'd be curious as to how much weight you could pull off something like that...
