I've just come across a pretty good deal on 30# injectors with a Pro-M 70mm MAF meter, and I am seriously thinking about picking them up.

My question is, will the injectors be too big and will the MAF be too small for my set up. Currently for mods I have; E-cam, Edelbrock Performer heads 1.90/1.60, 1.6RR's, Trick Flow street heat intake, BBK 70mm TB, Pro-M 75mm MAF meter, pulleys, full exhaust, stock 19# injectors with ajd FPR, and 255lph fuel pump.

Basicly, I want to know if the 30's will be over kill, and will it hurt going from a 75mm MAF to a 70mm MAF?

Thanks, Craig.

Injectors will probably be a tad big and meter is deffinetly too small.

Yeah I have 30lb injectors and they are a "tad big". It causes a hard start problem when hot...it doesn't ignite the "dumped" fuel as good when hot...and I get a rich idle (you can smell it)...

The MAF is to small if you would like more performance...but it will do you fine.

Well I have toyed with the idea of nitrous, or maybe building a 331. So I think the injectors might be worth it alone. He's selling both for $175. I'm more concerned with the MAF size though.

For that price buy them both, Craig. Sell the MAF once you buy it all. And are you sure it's a 70? Not a 73 or 75? The only 70mm MAF's that I know of came stock on sn-95's......

Well, the MAF is fine, but the injectors are way too big. Since you already have a 75mm MAF, I wouldn't even worry about it.
