[2] The first production car,[5] designated Tipo 105.64, was shown at the 1970 Geneva Motor Show and featured substantial changes from the concept car, using a 2,593 cc 90° dry-sump lubricated, cross-plane V8 engine with a bore of 80.0 mm and a stroke of only 64.5 mm using SPICA (Società Pompe Iniezione Cassani & Affini) fuel injection that produced around 200 PS (147 kW; 197 hp), coupled to a five-speed ZF manual gearbox and a limited-slip differential.

This engine was derived from the 2-litre V8 used in the 33 Stradale and in the Tipo 33 sports prototype racer but was detuned for increasing reliability.

The chassis and running gear of the production car were shared with the Giulia GTV coupé and comprised double wishbone suspension with coil springs and dampers at the front and a live axle with limited slip differential at the rear.

[4] Despite the name, Alfa Romeo chose not to submit the Montreal to emissions testing in the United States or Canada, and ultimately the car was never officially exported to those markets.

[2] This dampened the interest of the buying public which was already considering fuel efficient options due to the 1973 oil crisis.

After body fitment, the car was sent to Grugliasco to be degreased, partly zinc coated, manually spray painted and have the interior fitted.

The Autodelta race car had a 2,997 cc engine with maximum power output of 370 hp (276 kW) at 9,000 rpm.
