The hydraulic roller system, stock on all Magnum engines, is superior for producing horsepower and requires no maintenance. You could, theoretically, use a flat tappet LA camshaft in your Magnum engine, but we advise against it. Important note 3: You should ALWAYS check piston/valve clearance and retainer/guide clearance when installing a new cam. 550+ lift cam in our shop car, did not need to flycut the pistons, and have more than the minimum clearance. While max lift is related to cam duration and other factors, we are using a. 520 lift due to retainer/lock to valve guide clearance issues. Important note 2: There is a persistent rumor that the Magnum engine will not tolerate camshafts with higher than. Serious racers should seek a more robust solution than stock or cheap replacement pushrods, but those linked to above have served us very will in our shop car. These affordable stock replacementsР’В work well for most applications. Important note: On custom cams, the base circle is typically a little smaller than the stock Magnum cam, necessitating longer pushrods. Watch this space in the future for true performance camshafts available to Magnum swappers! We will have cams to order without the hassle of having a custom grind. Additionally, you can have it ground on an LA style cam core to get the proper snout for running a fuel pump eccentric if you want to run a mechanical fuel pump. For a little more than a shelf camshaft costs, the experts at CompР’В Cams will custom grind a camshaft for you, and youРІР‚в„ўll get you a cam specifically designed for your car and engine combination. The best camshaft solution is a custom grind. are intended for big trucks and low-end torque, rather than high RPM performance. There are some adequate cams from Mopar crate motors, but almost all of the shelf offerings from Comp, Crane, etc.

If youРІР‚в„ўre swapping the Magnum into a car, and youРІР‚в„ўre interested in performance and horsepower, shelf-stock camshaft options for the Magnum engine are limited. With a true 58cc casting such as the EQ Magnum or Edelbrock Performer RPM headsР’В youРІР‚в„ўll be in the vicinity of 9.5:1 compression with the stock short block. Cleanup is a snap as well.Р’В They seal well and increase compression significantly over stock. TheyРІР‚в„ўre about half the thickness of a stock gasket. We used Mr GasketР’В .028 thickР’В gaskets on our shop car, and weРІР‚в„ўve never had a failure or a leak. Fortunately, thereРІР‚в„ўs an easy solution for getting some of that compression back - opt for a skinnier-than-stock head gasket. This reduces compression potential, and thus horsepower. 050 inches down from top dead center on most engines. Magnum engines have more consistent machining than their LA predecessors, but the factory piston is still about. Edelbrock does not sell their Magnum heads with the LA intake bolt pattern. EdelbrockРІР‚в„ўs castings have the advantage of being aluminum, but are significantly more expensive than EQ heads, and may not flow as well. Details Here:Р”В®delbrock also makes heads for the Magnum. I think they are РІР‚Сљmissing the boatРІР‚Сњ a bit by not offering a Magnum compatible head with the LA bolt pattern. They are more expensive than the EQ and may not flow as well. They carry many of the same improvements as the EQ heads, with a slightly larger combustion chamber (62cc). RHS also makes improved iron heads for the Magnum (and LA). They even created a version with the LA intake bolt pattern. Being gearheads themselves, EQ designed heads that flow even better than factory castings. These heads, made by Australian company Engine Quest (also called EQ), were created as a stock replacement for the Ram truck guys (and gals) when their factory induction-hardened heads inevitably cracked. Through research, weРІР‚в„ўve found the best bang for your buck is a set of Engine Quest heads. Considering the affordability of some aftermarket options, and the performance gains realized with them, we think putting a new set of heads on your Magnum is a must.

This makes spending money to upgrade them dicey, at best. Unfortunately, they are prone to cracking between the seats. Magnum engines have some of the best flowing heads Mopar has ever released.

The key to horsepower is good cylinder heads. Attention to detail and a little extra money spent in the right places are the keys to success. As we have demonstrated with our shop Dodge Dart, it is possible to turn a junkyard engine into a real screamer. There are a lot of areas where the MagnumРІР‚в„ўs base horsepower can and should be improved.
