370's are marine injectors ... some company's sell modified 370's which have correct spray angle for our pistons. they are more expensive but worth it IMO

if the injectors are marine will they cause damage or premature wear to any components in my engine or is the problem with them that they just do not provide as much power as an injector that is intended for our trucks?

the marine injectors do not have the correct spray pattern for out pistons and they will spray " out of the bowl". out stock pistons are 145* and the marine pistons are 155*.
