If you're just taking a survey, that's one thing, but if you're looking for a recommendation, that's another. It'll depend on several variables: Head flow, camshaft, CR, etc.

I asked Bryan at PCMFORLESS which ones I should run based on the parts I selected for the 388 I was building. He recommended 30#; that's what I'm running.

So put me down for 30#.

50's with plans of going to 96's But I purchased a turbo car!!
Actually, injector size is based on HP rather then CID
The car in my signature is running stock injectors, but they are maxed out and its going lean on top end.

36# FMS but have ran 28's and 42's and all will tune to the proper AFR. The reason for so many injectors was with the 28's the DC were near 90% and I thought I had a problem with the 36's and bought the 42's but found out the problem was not my injectors so I changed them back to the 36's
