What size injectors,mass air,tb w/afr fti

[speedtrip]

Spending tax return ordered fti cam and will be getting afr 165 competition heads1404. I already have cobra intake and 65 tb ill probably upgrade to the edelbrock performer and 70 or 75 tb in the future.Wondering what others are using with this combo as far as injector,tb,mass air size.

30's, 75mm tb, 80mm pro m. Its what I use and what was recommended to me by Ed.

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.
