To most car crafters, the D100's original cast-crank 440 is ripe for picking and swapping. I'm also tempted, but I'll keep this rig intact and use it to pull a car trailer. A Camper Special, it has extra-duty cooling and upsized springs and brakes. A previous owner replaced the stock Carter Thermo-Quad with a 750-cfm Edelbrock Performer four-barrel. The mill runs great but has a leaky driver-side exhaust manifold, and the factory-issue pressure gauge is suspiciously sluggish. There haven't been any ugly noises so far, but I'll throw a high-volume Melling oil pump at it soon and see what happens. The 3.55 Sure Grip 9 1/4 rearend is perfect for burnouts.
