Bill Kirchen & Redd Volkaert - "Hot Rod lincoln" (Part 1)

Sorry, the Lincoln flathead V8 of the early 50s was significantly larger than the Ford and Merc version in both displacement and physical size. Looked like and industrial motor.

The original Hot Rod Lincoln by Charlie Ryan was running a flathead Lincoln V-12 (Hot Rod Lincoln). 12 cylinders but the bore, thus displacement, was relatively small. The intent was to give a smooth running motor. Commander Cody changed it to the more common V8 flathead.

What's the name of the song at 2:51?

The original line is "Twisted the speedometer cable off the end."

Nope. "Twisted the speedomer cable off then". Listen to it.

Well, I would never argue with an expert but the lyrics are filed at the BMI site and are easy to check.  I've been performing this song for close to 50 years but guess you know more than I do so I'll change it. By the way, the song refers to a 12 cylinder Lincoln Zephyr engine, the flathead V-12 used in the Lincoln Continental of the late 30's and 40's. The lyrics are "got 12 cylinders, use 'em all, with overdrive, it just won't stall. It's not a big inch dual quad V8 Lincoln. Look it up.

The original Hot Rod Race came out in the early 50's. Charlie Ryan wrote this and recorded it in 1960. His original version is on You Tube. W S Stevenson is often credited as co-writer but he was the guy who owned a record/publishing company in Pasadena in those days and insisted on taking half or more of any song he recorded. The first big hit on this was by country singer Johney Bond, who changed some of the lyrics. Commander Cody did it in the 70's. IMHO Bill Kirchen's version is #1.

in the commander cody version, it's a v-8
but the lincoln zephyr 12 cylinder makes the song way better.

AFAIC this is the best version of all. The song originally was written as a response or sequel to "Hot Rod Race" by Arkie Shibley which came out in the late 40's or early 50's. The first line of "Hot Rod Lincoln is "You've heard the story of the Hot Rod Race where the Lincolns and Mercury were setting the pace, that story is true I'm here to say, cause I was drivin' that Model A."
