So you wanna beef up your LB7.
Well heres a few numbers to toss around. These are from my buildup.
Mahle Pistons w/remachined bowls, thermal coating and lubricty coating:$2,300
Carrillo Rods $3,125. There are cheaper rods though too. The cheapest being about $2,400
Billet Main Caps $600
Billet Injector Clamps $400
Injector Studs $180
Head studs $660
ATI Super Damper $440
Banks Flex Plate $??
and then all of the seals, the new water pump, the new oil pumps, and all of the machine work.
It aint cheap to beef up a duramax.
