Default Injectors

I have a stock 87 I purchased a cold air intake and 70mm sensor,throttle body and EGR plate I was looking for injectors and was wondering if anyone could tell me what I need and where to find them. Thanks

Have you converted to mass air? You said you picked up a 70mm sensor...What size injectors is that sensor calibrated for? For a completely stock 302 ie no cam, intake, or heads, your throttle body is really too big. If you want to use that 70mm, keep in mind there are forced induction guys running 65mm tbs, I would upgrade to at least an explorer or cobra intake and then go to 24lb injectors, available on any number of mustang parts websites, ie American Muscle, 5.0 Resto, ...

I run 30lb injectors and a 70 mm on my 347, and ran 24lb when it was stock 302.. I do spray 300hp in the 347 and seems to work well. If you are gonna turbo it, you will want even bigger injectors. But like pete88gt said, you will need injectors that match you MAF Sensor.

Maybe I just don't understand something, but why would anyone run bigger injectors and a larger TB/EGR spacer and mass air if they haven't already built the 347 short block?

Do you really gain anything to justify going larger while still using a stock 302? I mean if this is for more performance before building the short block wouldn't the heads be a better choice? Maybe even a mild cam would give better performance than simply those minor things?

There is no reason to upgrade your injectors with stock heads still on the motor.
