Our goal is simple: Keep Vintage Mopar engines in Vintage Mopars!
The rationale for that is simple as well; in that we have found that with some straightforward old-school hotrodding, there is no need swap in a V8, let alone a Chevy, into your rare & unique old Chrysler, Dodge, DeSoto, or Plymouth.
We have over 80-years of combined experience with building and tuning Mopar flatheads in our own cars; mildly hopped-up daily drivers, traditional hot rods, speedsters, and race cars. Granted, it's pretty exotic, but our little 212" 1928 Dodge flathead ( www.fastfourspecial.com ) produces about 240 RWHP, and has set twelve landspeed records at Bonneville and El Mirage. But believe it or not, that research is applicable to your '36 Plymouth coupe. We drive our inline six-Mopars daily, and we all also own and have built many more "hopped up" flathead sixes and eights over the years, including a '33 Dodge for the 2019 Peking to Paris Rally.
Our five-step program is perfectly straight-forward:
- Additional Air/Fuel
- Improved cam timing, duration & lift
- Increased compression
- Better exhaust flow
- Overdrive and/or change rear end gearing
The Montana Dodge Boys are very excited to make some of the products that we have been experimenting with on our own cars for over 22 years available for sale to the public, many for the first time!
We have an intense, admittedly bizarre passion for early inline Mopars, and we admit we're a little wacky and our perspective is also a bit off, so we need your help as we develop our product line.

We have been racing our vintage Mopars on the Bonneville Salts since 2002, and our experience and success has fostered several unique relationships with world-class performance vendors; CP pistons, Carrillo rods, Moldex cranks, Edelbrock, Vortech, ARP, DynoJet, Race engine systems, MSD have all had a hand in our twelve vintage landspeed records.
Our partner EDGY Speed Shop was founded in 1995 by Earl "Edgy" Edgerton of Santa Rosa, California after learning to grind vintage cams from his mentor, Rod Furtado. His cam profiles are from legendary cam grinder, John DeLong of DeLong Cams.
In 1998, Earl made his first hand-drawn pattern for a high-performance aluminum cylinder head for Dodge/Plymouth (201/218/230) L-head sixes. The proprietary high-performance combustion chamber design has been proven on both his own 1933 Chrysler coupe and by the Montana Dodge Boys, who campaign their Fast Four Special on the Bonneville Salt Flats, and have captured twelve Vintage Flathead Landspeed records. He later also created a pattern for the larger Chrysler (251/265) sixes.
In 2003, Earl became intrigued by the famous Riley F-heads for Ford Four Bangers, and used that inspiration to design his own F-head for both the Dodge/Plymouth and larger Chrysler sixes. While only a few have been produced, they have become legendary amongst vintage Mopar enthusiasts.
