Long Tale of Woe

A few years back I decided to rebuild the 440 in my GTX. I was getting some blow-by, and wanted a little more horsepower than that from the factory. I sent it to my local machine shop and had it rebuilt. I purchased a new COMP cam with lifters and springs to match. Break-in oil and lube was installed, and the cam was broken in to COMP’s specs. It sounded great and ran great—for as long as it held together. a

Three Simple Steps to Big Flow Gains
Three Simple Steps to Big Flow Gains
There’s a saying that when it comes to engine building, “the power is in the ports.” Airflow is the key to turning up the power output of any engine, and with choices in performance cylinder heads, there is plenty of flow to be had.

There’s a saying that when it comes to engine building, “the power is in the ports.” Airflow is the key to turning up the power output of any engine, and with choices in performance cylinder heads, there is plenty of flow to be had. However, when money is tight, budget constraints often dictate cylinder head selection. We see plenty of Mopar street machines running around with OE cylinder heads. Sure, a swap to aftermarket heads might be in the cards for later when the funds are available, but is that a reason to give up substantial horsepower right now? Port work can improve the situation substantially, but grinding on that old iron has its practical limits. Professional porting cost bucks, and unless the engine is being built for a class that demands stock iron, it’s generally impractical. That said, is it worth pulling out the tools and giving the heads a little rework? If you can handle a grinder, the answer is almost always “yes.”

Smoothing Steel Bumpers
Whether you prefer paint, powdercoating, or just good old chrome, those two hulks of press-formed steel hanging off the front and rear of your car often need some attention.

Whether you prefer paint, powdercoating, or just good old chrome, those two hulks of press-formed steel hanging off the front and rear of your car often need some attention. Bumpers are there for one real reason—to protect the car in low-speed accidents, but they can also bring style and flare to your car’s body in a unique way. When building a custom ride, the bumpers can serve as an excellent opportunity to show off your design skills, if you have the nerve.

Nowadays, we have an ample supply of aftermarket and restoration parts that at one time, we never imagined possible. Once in great while, a product comes along that’s so simple and innovative, it’s mind blowing.

Nowadays, we have an ample supply of aftermarket and restoration parts that at one time, we never imagined possible. Once in great while, a product comes along that’s so simple and innovative, it’s mind blowing. With Aeromotive’s latest Phantom/Stealth fuel system, you can have a quiet, hidden (the fuel pump fits inside the stock tank) setup that can support up to 1,000 horsepower in a carbureted application, or 825 horsepower with EFI—naturally-aspirated for your Mopar monster.
