Sherman M4A2 Detroit Injectors

[Andrew Rowe]

You are right in the fact that more diesel requires more air. There are the standard old liners that had a couple of rows of small holes all the around the liner and then for the bigger injectors there are liners with large e-elongated holes. You can view what type of liner you have by removing one of the little side covers on the side of the engine, and that will indicate whether the engine will appear to have been built matched to the injectors. There are quite a few different configurations that can interchange on these motors , from injectors to liners to different heads, 4 valve to the old "low block" 2 valve head. To get the power with bigger injectors the 4 valve head is needed. Cheers Andrew
