ALTERNATIVE FUELS GM Chevy 350 5.7 Long Block 1996-2010 #880 4-Bolt Main - CNG, LNG, and Propane

Details

Compressed natural gas (CNG), liquefied natural gas (LNG), and propane are known as “dry fuels” because they provide little or no lubrication to the valves and seats during engine operation. Consequently, rapid wearing and failure of the valves and valve seats is common on engines operating on alternative fuels.

Because of its location in East Texas, MABBCO has been providing engine related services to the Louisiana oil field and Texas agricultural sector for over half a century.  In that time, MABBCO has developed a particular expertise in remanufacturing engines operating on alternative fuels.  MABBCO alternative fuel engines are well suited for stationary applications, as well as, cars, truck, and taxis.

MABBCO alternative fuel long blocks are remanufactured with a true nickel based valve seat designed specifically for use with alternative fuels.  Both the intake seats and exhaust seats are replaced.  All valves are replaced with stellite exhaust valves and stainless steel intake valves.  No rotators are installed.  This combination maximizes cylinder head life.  For customers wanting to better understand the demands of alternative fuels an informative article can be found at https://www.enginebuildermag.com/2015/05/cng-and-propane-engine-builds/
