attention all gear heads......

I'm in process of building a 88 hatch gt, have built 331 with stock injectors and Cobra intake, t/f cam and x code heads. Have Cai and ordering new Maf but want to know what injectors I should use

If staying naturally aspirated then 36lb/hr will work fine.

At least 36lbs. You will really find out if you need larger injectors when you dyno tune it

What about a bone stock motor with bbk SSI intake, Cai, headers, and maf. All bbk but running stock injectorsand seems really lean, like burns your eyes lean. It's a 92 gt with stock cam but motor is .030 over. It has an idle demon and timing sounds off due to valve rattling under load but am running 12 degrees btdc and premium fuel. What size injectors should be in this one ??

Burning of the eyes is burning too much gas.

Again, doesn't sound like it is burning too much, sound like not burning enough, therefore there is more vapors that aren't being burned off

Sorry that's what I meant... Either too much fuel is being dumped or not enough spark in the cylinder to burn all the gas supplied

Ah ok, that makes sense, now we are on the same page. That being said I had a similar problem with the 347 stroker in my Lincoln, and I believed I fixxed it by installing a msd box.

I just finished installing 30# injectors and my crazy idle calmed down, car runs cooler and the fumes are gone ! My problem was fixed but I had 2 injectors that fell apart as I was taking them out so may have had another issue there too. But its all good
