Injector size question.
Posted: October 24th, 2018, 2:24 pm
Question for you guys. ( i searched on here and have been researching for hours)
I have a fresh rebuild 4.0 HO. Bored .030 and Has comp cams X4250H-13 and 9.1 to 1 CR. The rest is stock. Will have the reduced portion of pipe (just after collector) gone before i fire it up. Also higher flowing muffler.
Stock size injectors be OK? from what i read they are 22lb but since std pressure is 31/39 its 21lb actual.
or should i go to 24lb. ???
I also considered stock size and adjustable regulator. But until i put the wideband on it i just want it to be safe. It plugged #1 injector and broke the top ring. Thats the reason it came out for rebuild. So im ordering 4 hole injectors but want to get the proper size.
Thanks in advance for any info/advice. Dave
