TCM 1050 EFI

The most versatile engine in the Teague Custom Marine line is the TCM 1050 EFI. Evolved from the overwhelmingly popular TCM 900 EFI, this higher compression "stroker" engine features only the best components on the market.


It is configurable for use in most any application, from single engine bravo style installs with CMI Sport Tube headers, to twin engine M6 surface drive installs with CMI Big Tubes! The TCM 1050 is based upon a tall deck World Merlin IV Billet Splayed Main Caps block, with a Callies Magnum or optional Sonny Bryant Racing crankshaft, Carrillo connecting rods, proprietary AFR CNC 24 Degree Hard Anodized Heads, and T&D Steel Shaft Roller Rocker Systems, this 548 cubic inch engine may be in the middle of our line, but is far from mid-range in quality.


850 EFI

Configured with the new 4.5L Whipple Twin Screw Supercharger and low-profile twin core MOAIC Cupronickel Intercooler, which is fed by a full stainless steel twin or triple stage Latham water pump, the TCM 1050 EFI is the cool air charge temperature and efficiency king.


Featuring high RPM rated, short travel Johnson hydraulic lifters, and a proprietary LS1 firing order camshaft, maintenance is kept to a minimum and valve lash adjustments are eliminated. The TCM 1050 EFI is finished with fully color matched billet aluminum accessories and custom plumbing, combined with custom supercharger and valve cover powder paint options for a truly custom engine installation.
