Default Injector ubgrade with Lloyd's 223/230????

Hey guys I have a quick question for you all. I am going to be doing a cam change in my car as soon as my tax return check comes in the mail. I am going to be doing Lloyd Elliott’s 223/230 with stock heads. My question is, is it necessary to upgrade my injectors when doing this cam swap?

Just for further information I do squeeze a 150 wet shot. But I am assuming that since it is wet it should take care of its fuel demands on it own.

YES.
I had replace my upgraded 30# SVO injectors which were going above 90% DC to 37# injectors. Stockers will not do the job and will most likely fail.

If you have the money, I would upgrade the injectors. Stock ones might work though. With a 150 wet, you should definitely upgrade your pump if you haven't done so already.

I would just keep my eyes peeled in the classifieds section. I bought some NIB cobra 39# injectors for 175 shipped when I was rebuilding my '97 SS.

I ran a similar cam with 30# SVOs.
Look for something in the 30-36# range. (although 37-42# would work too and give you room to grow)
They don't have to be SVO, Racetronix (lucas) work well too (as do many other brands).

You can usually find injectors for sale in the classifieds section.
Buying used is a bit of a gamble though since you don't know the history and
having them cleaned/flow tested is almost as expensive as buying new ones.

No matter what you get, make sure your tune is configured properly or you'll end up running rich in open loop.
