Reilly Motorsports’ Street-Lynx Rear Suspension Install

For the rear suspension of our ’69 Charger (Project 50), we felt that the versatility of a four link would be just what the car needed. After all, this car will be driven, autocrossed, and drag raced.Ok, let’s get overly simple: Your classic Mopar has

Refinishing the Tail End of A 1973 Dodge Challenger

For the past 30-something years, your author has noticed that many of the 1972-74 Challengers have had their tail panels blacked-out. While black is beautiful and looks good, we wanted to go back to the stock look.For the past 30-something years, your

Is there really that much difference in headers?We often try our best to get the most performance possible from our engines. In the search for more power, we often remove exhaust manifolds and swap them out for a set of headers. Available in various co

Power Gains with a cam Swap

A camshaft swap is not a lot of work to perform, in order to receive what could be the greatest gains in power that an engine can experience. The camshaft is one of the main determining factors in an engine’s potential to make power—especially within a given rpm range. Since the affected power band is different depending on the camshaft, one the most important aspects to consider when selecting a camshaft, is to have a realistic, specific rpm goal in mind before you begin. If you are changing the camshaft to get more low-end grunt, choose accordingly. On the other hand, gaining maximum high-rpm horsepower takes an entirely different set of camshaft dimensions. Lying to yourself about what you actually need as opposed to what you actually think you want, has caused many car guys to park their rides and lose interest because the car is no longer enjoyable to drive. We want to help you avoid that particular scenario. In our August 2014 issue of Mopar Muscle, we installed three different camshafts in a late-model 5.7 Hemi, to see just what kind of changes would take effect. We noticed that our mild engine did like more lift, bust adding duration took the power band beyond our engine controller’s limits. If you want to read the whole story, check out the August 2014 issue. If you’re tuning in here to see what the dyno graphs look like, then check them out;

Mopars have long been known for their prowess on the street and drag strip, but while classic Mopars—with their one-piece differential housings—are well suited for drag racing, when it comes to touring or road course racing, they leave a lot to be desired.

Since the introduction of the new, late-model Challengers, Chargers, Magnums, and the Chrysler 300s, we have to admit that the performance offered by these vehicles is outstanding. In fact, we’ve driven, modified and tested several late-model vehicles in the pages of Mopar Muscle, and have always been impressed by their manners both on the road and at the track.

How to Replace a Dodge Challenger’s Floorboard – Floorboard Fix-Up
How to Replace a Dodge Challenger's Floorboard - Mopar Muscle Magazine
We had thought about repairing the floors with some old road signs and beer cans that we have collected over the years, but decided that this car deserved better.

Last month, we showed you an E-Body that had its torsion bar crossmember and front floors completely hacked. We couldn’t understand the reasoning for the extent of the hacking, but it was done nonetheless. So, we replaced the crossmember, and now it’s time to tackle the floor. We had thought about repairing the floors with some old road signs and beer cans that we have collected over the years, but decided that this car deserved better. So, proper metal it is. We all know about AMD, and the metal that they have been producing, so it was an easy choice where to get what we needed. The AMD metal has OE-style coverage like the original piece in the car—minus the big cut-outs made by someone. It mates to all surrounding OE panels and pieces with OE dimensions. It even comes with a proper flange on the side to correctly fit with ’70-style rocker panels. It also includes bucket seat, emergency brake cable and speedometer cable brackets. What more could you ask for?

How to Install Comp Cams’ Solid Roller – Get Rolling
How to Install Comp Cams' Solid Roller - Get Rolling - Mopar Muscle
Can a solid roller cam improve street driving, track performance, and broaden the power band? Check out how we installed Comp Cams’ solid roller on a 1964 Plymouth Fury!

If one thing truly leads to another, you can say the head and exhaust swap we performed on the Balls of Fury (Charlie and Chad Pirchio’s ’64 Sport Fury) in the August ’13 issue (Two Bolt-ons Bring 81 Horsepower) led us to this cam swap. We felt we were leaving a bunch of power on the table with the hydraulic flat tappet cam profile that was in the 440, ergo, we put in a call to Comp Cams thinking we could harness that power with one of their modern, solid roller designs.
