I had a combination similar to yours.

- AFR 165
- FTI camshaft
- Ported Performer

I was running 30 lb injectors. They did okay. With the 300 or so rwhp I had, I would have liked the 24 lb injectors since I was not getting a tune.

A 70mm TB will be fine with an 80mm MAf up front.

Good Luck.

Since Ed designed the cam...
Ed is the BEST qualified person to answer this question.

Ed told me that if I was to get a tune, the 30 lb injectors were going to be the way to go.

I was not getting a tune, but I bought them just in case.

30 lb injectors will be fine for you.

You are not going to gain very much by going to a Performer from a Cobra. The Holley would be a much better choice IMO.
