Engine Installation Good things about Alfa Romeo Spider engines: aluminum engine blocks with cast iron liners, forged steel crankshafts with five main bearings, aluminum cylinder heads with hemispherical combustion chambers and centered spark plugs, and dual overhead camshafts driven by double-row timing chains. There was no need to upgrade this car's radiator or cooling fan. Alfa Romeo Spider engines feature a large, finned, 7-quart capacity oil pan. They have a reputation for running cool. The stylish aluminum brace across this engine bay would tie together the strut towers, if only there were strut towers. It was adapted from some other car. Stock 1974 Alfa Romeo cast iron exhaust manifold. SPICA (Societˆ Pompe Iniezione Cassani & Affini) mechanical fuel injection. Decal: "2000 Iniezione Sistema Alfa Romeo - Spica, Patented 3146770 - 3312208 - 3577978" A clothesline reel is used to limit travel of the front clip. Suspension and Brakes Stock 1974 Alfa Romeo Spider wishbones, coil springs, and telescopic dampers. Interior Alfa Romeo "Personal" steering wheel. Stock 1974 Alfa Romeo instruments, left to right: tachometer (0-8000rpm), speedometer (0-140mph), fuel level, oil pressure, and coolant temperature gauges plus an air speed indicator gauge, an artificial horizon, and an altimeter. (All these guages are functional.) Plate in center says: "Lock Will Not Release With Wheels Off Ground". At right, a graduated brass lever from a Fairbanks Scale. 18-pound brass gyroscope off a Japanese WWII-era 3000 pound torpedo. Manufactured by Mitsubishi in Nagasaki Japan, it's still in its original wooden shipping box. A U.S. Navy Colonel brought it home as a souvenir. Exterior Steve's Tadpole - "a little frog with a tailfin" - weighs about 600 pounds less than the original 1974 Alfa Romeo Spider did before the body transplant. Steve commented: "It's amazing how much rubber bumpers and roll-up windows add to the weight of a sports car." Especially since the Tadpole is so much lighter than a regular Spider, it will benefit from a change of rear end gearing. Currently, it's using stock 4.56:1 gears. Steve has a 3.60:1 ring and pinion set from a rare automatic-transmission Spider to install when time permits. "Yes, I mated an Italian Spider with a British frog. Foreplay took 4 years." The red tongue is a bent propeller tip. Steve notes that it serves as a nerf bar and "it's stronger than the plastic bumper on any new car." 1953 Pontiac Chieftain hood ornament. Steve made headrest fairings out of the tips of an aluminum canoe. Steve purchased the canoe for the price of the scrap aluminum. Joseph Pollak Co. of Boston Massachusetts manufactured this battery disconnect switch.
