GM V6 Production Figures
Written by Brian McCullough
The GM 60 degree V6 started life with a displacement of 2.8 litres or 173 cubic inches. These early units started as a progressive two barrel carburetted induction with a mechanical advance distributor and has since been updated several times. In later years it became a 3.1L and the most commonly used motors are now the 3.4L ~ 204 C.I. V6. GM continues to produce this motor and with support from sites like ours, continue to make this a very popular conversion motor for vehicles the need speed and still wish to remain well balanced and easy to maintain. This engine changed much the same as GM’s 265 V8 became the well known 350 C.I. V8 over time. GM has announced future use of the GM 60 Degree Vee-Six engine with continuing technical and displacement alterations in the future that will continue to benefit all of those using the system for their products which has already given a trickle down effect to those of us using these motors in conversions and the street rod form.
Besides for the 2bbl variable progressive venturi, this motor also came out in Throttle Body Injection (TBI), Multi Port Fuel Injection (MPFI) as well as Sequential Port Fuel Injection (SFI). Aftermarket support also allows for the use of a high-rise two or four barrel intake system, aftermarket injection control systems, retrofitted turbo and supercharger systems and many more options as well. Ignition systems also varied from a mechanical/vacuum advance distributor to computer controlled and all the way up to Distributorless Ignition Systems. Our kits allow for the use of the cast iron head motor in all these varied configurations and reduce the weight of cars such as the MG B by 30 pounds. We have other systems that allow for alternatives to the standard motors with more BHP and Torque, depending on the required final results.
BMC British Automobile’s original goal was not to add cubic inches as much as to combine modern technology to classic British vehicles without detracting from the handling, braking or aesthetic characteristics... but the average Stock motor streetable 185+ BHP with 230+ foot pounds of Torque has not hurt any!
