My 5.7 has a big over 210k miles, 338k km, and the only engine specific work, that wasn't routine like plugs and wires, was the main fuel injector, some kind of gasket on the intake or something not the head gasket, and that's it
Pros: reliable, easy maintenance
Mileage: 338000 km
Holy ****, they fit. FOUND IT. The injector that has been so elusive that flows more than stock (exact % will not be disclosed at this time as I do not want to upset any advertisers with my findings....) is from the GM 2.0 Ecotec motor: - GM LNF 2.0 ECOTEC OEM Injector Part # / Bosch Part # : 12636111 / 0 261 500 112.
Pros: flows more than stock
Part number: 12636111
