This 1,290cc inline-four was produced for use in a 1969 Alfa Romeo Giulia Spider 1300 Junior or Giulia 1300 GT Junior and was bored .040″ over when it was reportedly rebuilt by Huffaker Motorsports for installation in a Huffaker-Genie MKIV that was acquired by the owner in 2017. The engine was subsequently removed, and it is fitted with twin Weber carburetors, a camshaft cover, ignition components, and a dry-sump oil system. This Alfa Romeo engine is now offered by the seller on behalf of the owner at no reserve in Oklahoma City, Oklahoma.
The Alfa Romeo twin-camshaft 1,290cc inline-four debuted in 1954 with the introduction of the Giulietta Sprint coupe. The design features an aluminum block and cylinder head, cast iron cylinder liners, and hemispherical combustion chambers. Per the seller, this example was rebuilt in 2017 by Huffaker Motorsports. The seller reports that the engine was used for around five hours across two race weekends in a Huffaker-Genie Mark IV before it was removed and stored.
Dual Weber 40 DCOE 28 carburetors are installed. The engine was bored .040″ over, and modifications are said to include a dry-sump oil system, a revised crankshaft, CP-Carrillo connecting rods, and JE Pistons and Total Seal piston rings.
Double overhead camshafts are housed under an aluminum cover that displays the Alfa Romeo script. A steel oil filler cap is secured to the cover. Photos of cylinder leak-down test results are included in the gallery.
Serial number AR00530☆27279☆ is consistent with an engine destined for installation in a 1969 Giulia 1300 GT Junior or Giulia Spider 1300 Junior.
