I have a set of 2nd gen 370s and i was wondering if i could throw the nozzles in my 92 bodies. They might not be 370s but they are way bigger than stock holes and the truck ran good so im thinking about trying them.

 

you can swap nozzles but pop pressure should be reset. make sure your 2nd gen nozzles are for sure bigger (holes). older marine 370s often had a wider spry pattern but should have 5x.0012 holes. better than stock i/c injectors

 

How do you reset pop pressure?

 

If the injector tip's are for a second gen the spray angle would be wrong for a first gen. I believe this will cause excess blue smoke at idle and haze while driving, plus they would not make as much power as the same tips with the proper spray angle.
