farmboystoy 12-13-2006, 11:27 AM What would the compression ratio be if a guy had the thick gasket on a LB7 and the rods where bent .050? Just wondering how low we can take the compression and still start them in the cold. This truck started ok. Thanks Roger DURAtotheMAX 12-13-2006, 12:45 PM I think Clint at ATS runs 15:1 pistons in his truck and theyre in colorado...

Will start quicker on ether than glow plugs with low compression. farmboystoy 12-14-2006, 10:28 AM Unhook the glow plugs. Will start quicker on ether than glow plugs with low compression. Good idea:) Thanks Diesel Power 12-15-2006, 04:09 AM my original 02 engine had thick gaskets and all rods were self-shortened, the worst being .048 under the deck. truck had no intake air heater and always started perfectly MDE 12-15-2006, 07:47 AM 12:1 with glow plug, 13.5 without glow plug by 32 degrees F farmboystoy 12-15-2006, 09:27 AM Thanks guys:) Just trying to decide how low I should take my compression.
