Iron Headed: 23-Degree Modified Combustion Chamber
In the past, a set of iron heads for domed or flat-top piston applications meant a lot of extra machining. You can forget about the added expense as Engine Quest now produces a 23-degree cylinder head that will accept either type of piston with its newly constructed combustion chamber design. These cylinder heads come available in 180, 200, 220, or 235cc intake runners and come with a standard 64cc combustion chamber and angle plug. If you need a smaller chamber, Engine Quest also offers a 50cc option. Additional features include a thick 0.4375-inch deck for strenth, hardened DuraBond exhaust seats, and Phospor bronze guides.

Plus One Advantage: Overdrive 700-R4 Transmission
Most Turbo 350 and 400 three-speed transmissions only allow for street cruising with limited rpm revability on the freeways. That's changed with Monster Transmission's latest 700-R4 overdrive conversion upgrade. The package has the advantage of an additional overdriven gear that creates a 30-40 percent gain in fuel economy with higher top speeds. Monster's kits are bolt-in ready, come with a 3-year unlimited mileage warranty, and free shipping too!

Stealth Lighting: Hidden Side Marker Lens
Anvil Auto has created the "Phantom Lens," which replaces the chrome pot metal bezels on the side marker lights for '69 Camaros and Chevelles. The lenses are constructed with an injection molded polycarbonate and are designed to be painted to match the car's body for a hidden appearance. Black vehicles can use them right out of the box. And, since these kits are practically universal, they can be applied to an array of muscle cars and only require you to cut the sheetmetal with the supplied template. The sidelights are visible when on, and disappear when off!
