Injector Spray Pattern
#3
#6
Im not 100% sure if 160 and 175s had 4 or 5 hole but I do know that marine 300 and 330s are 4 hole. Have you tried them? They will work but will smoke a little more than they should and make more heat than they should. Marines are a goodcheap injector if your making power on the cheap but for a little bit more you can get 145 spray. Honestly I would rather have 215s over 300s or 330s
